Die Tränen des Henri Quatre
No full textDer vorliegende zweite Band mit Texten aus dem Nachlass von Dieter Adelmann (1936–2008) macht eine der letzten Arbeiten, die ihr Verfasser anlässlich seines 70. Geburtstags aus der Hand gegeben hat, für ein breites Publikum zugänglich. Der Essay bildet dabei einen Abschluss von Adelmanns ersten, im weitesten Sinne philosophischen Publikationen, die nach der Doktorarbeit (Bd. 1 der Nachlasspublikationen) entstanden sind. Ausgehend von einer Beobachtung in Heinrich Manns epochaler Doppelromanbiografie des navarresisch-französischen protestantischen Königs Henri IV. untersucht Adelmann die Tränen- und Todesmetaphorik in dem Romanwerk aus den 1930er Jahren. Von hier aus wird eine Brücke zur literaturwissenschaftlichen Ästhetik und Erkenntnistheorie Walter Benjamins geschlagen, mit der sich Adelmann bereits in seinen Arbeiten zur Politkunst Klaus Staecks beschäftigt hatte. Dabei deckt der Verfasser Fehlinterpretationen der Benjaminschen Theorien durch dessen Freund und Nachlassverwalter Theodor W. Adorno auf.This volume, the second in the series of the posthumous works by Dieter Adelmann (1936-2008), makes accessible one of the last works the author wrote. At his 70th birthday Adelmann surprised his friends with this essay which builds a bridge to the first philosophical writings after the 1968 dissertation on Hermann Cohen (vol. 1 of this series). In the beginning of the 1970s Adelmann had worked together with the artist Klaus Staeck whose political art was backed up with Adelmann’s philosophical considerations. In this particular essay Adelmann’s point of departure is Heinrich Mann’s 2-volume biographical novel on the French king Henri IV from the 1930s. Within that novel Adelmann is mostly interested in the metaphors of tears and of death. These metaphors are compared with Walter Benjamin’s aesthetics and epistemology which Adelmann already in the 1970s had analysed. He discovers some wrong interpretations of Benjamin’s thought by Theodor W. Adorno
Gallium adsorption on (0001) GaN surfaces
No full textWe study the adsorption behavior of Ga on (0001) GaN surfaces combining experimental specular reflection high-energy electron diffraction with theoretical investigations in the framework of a kinetic model for adsorption and ab initio calculations of energy parameters. Based on the experimental results we find that for substrate temperatures and Ga fluxes typically used in molecular-beam epitaxy of GaN, finite equilibrium Ga
surface coverages can be obtained. The measurement of a Ga/GaN adsorption isotherm allows the quantification
of the equilibrium Ga surface coverage as a function of the impinging Ga flux. In particular, we show that
a large range of Ga fluxes exists, where 2.5 +/- 0.2 monolayers (in terms of the GaN surface site density) of Ga are adsorbed on the GaN surface. We further demonstrate that the structure of this adsorbed Ga film is in good agreement with the laterally contracted Ga bilayer model predicted to be most stable for strongly Ga-rich surfaces [Northrup et al., Phys. Rev. B 61, 9932 (2000)]. For lower Ga fluxes, a discontinuous transition to Ga monolayer equilibrium coverage is found, followed by a continuous decrease towards zero coverage; for higher Ga fluxes, Ga droplet formation is found, similar to what has been observed during Ga-rich GaN growth. The
boundary fluxes limiting the region of 2.5 monolayers equilibrium Ga adsorption have been measured as a
function of the GaN substrate temperature giving rise to a Ga/GaN adsorption phase diagram. The temperature
dependence is discussed within an ab initio based growth model for adsorption taking into account the
nucleation of Ga clusters. This model consistently explains recent contradictory results of the activation energy describing the critical Ga flux for the onset of Ga droplet formation during Ga-rich GaN growth [Heying et al.,
J. Appl. Phys. 88, 1855 (2000); Adelmann et al., J. Appl. Phys. 91, 9638 (2002).]

Non-Binary Spin Wave Based Circuit Design
No full textBy their very nature, Spin Waves (SWs) excited at the same frequency but different amplitudes, propagate through waveguides and interfere with each other at the expense of ultra-low energy consumption. In addition, all (part) of the SW energy can be moved from one waveguide to another by means of coupling effects. In this paper we make use of these SW features and introduce a novel non Boolean algebra based paradigm, which enables domain conversion free ultra-low energy consumption SW based computing. Subsequently, we leverage this computing paradigm by designing a non-binary spin wave adder, which we validate by means of micro-magnetic simulation. To get more inside on the proposed adder potential we assume a 2-bit adder implementation as discussion vehicle, evaluate its area, delay, and energy consumption, and compare it with conventional SW and 7 nm CMOS counterparts. The results indicate that our proposal diminishes the energy consumption by a factor of 3.14 × and 6 ×, when compared with the conventional SW and 7 nm CMOS functionally equivalent designs, respectively. Furthermore, the proposed non-binary adder implementation requires the least number of devices, which indicates its potential for small chip real-estate realizations.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Computer EngineeringQuantum & Computer Engineerin
Spin Wave Based Approximate Computing
No full textBy their very nature Spin Waves (SWs) enable the realization of energy efficient circuits, as they propagate and interfere within waveguides without consuming noticeable energy. However, SW computing can be even more energy efficient by taking advantage of the approximate computing paradigm as many applications, e.g., multimedia and social media, are error-tolerant. In this paper, we propose an ultra-low energy Approximate Full Adder (AFA) and an Approximate 2-bit inputs Multiplier (AMUL). AFA consists of one Majority gate whereas AMUL is built by means of 3 AND gates. We validate the correct functionality of our proposal by means of micromagnetic simulations and evaluate AFA's figures of merit against state-of-the-art accurate SW, 7nm CMOS, Spin Hall Effect (SHE), Domain Wall Motion (DWM), accurate and approximate 45nm CMOS, Magnetic Tunnel Junction (MTJ), and Spin-CMOS FA implementations. Our results indicate that AFA consumes 38% and 6% less energy than state-of-the-art accurate SW and 7nm CMOS FA implementations, respectively. Moreover, it saves 56% and 20% energy when compared with accurate and approximate 45nm CMOS counterparts, respectively. Furthermore, it provides 2 orders of magnitude energy reduction when compared with accurate SHE, accurate and approximate DWM, MTJ, and Spin-CMOS, counterparts. In addition, it achieves the same error rate as approximate 45nm CMOS and Spin-CMOS FAs whereas it exhibits 50% less error rate than the approximate DWM FA. Last but not least, it outperforms its contenders in terms of area by saving at least 29% chip real-estate. AMUL is evaluated and compared with state-of-the-art SW and 16nm CMOS accurate and approximate designs. The evaluation results indicate that AMUL energy consumption is at least 2.8x and 2.6x smaller than the one of state-of-the-art SW and 16nm CMOS accurate and approximate designs, respectively. AMUL has an error rate of 25%, whereas the approximate CMOS multiplier has an error rate of 38%, and requires at least 64% less chip real-estate than the CMOS counterpart.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Computer EngineeringQuantum & Computer Engineerin
Spin Wave Based 4-2 Compressor
No full textBy their very nature, Spin Waves (SWs) consume ultra-low amounts of energy, which makes them suitable for ultra-low energy consumption applications. In addition, a compressor can be utilized to further reduce the energy consumption and enhance the speed of a multiplier. Therefore, we propose a novel energy efficient SW based 4-2 compressor consisting of 4 XOR gates and 2 Majority gates. The proposed compressor is validated by means of micromagnetic simulations and compared with the state-of-the-art SW, 22 nm CMOS, Magnetic Tunnel Junction (MTJ), Domain Wall Motion (DWM), and Spin-CMOS technologies. The performance evaluation shows that the proposed compressor consumes 2.5x less and 1.25× less energy than the 22 nm CMOS and the conventional SW compressor, respectively, whereas it consumes at least 3 orders of magnitude less energy than the MTJ, DWM, and Spin-CMOS designs. Furthermore, the compressor achieves the smallest chip real-estate. In summary, the performance evaluation of our proposed compressor shows that the SW technology has the potential to progress the state-of-the-art circuit design in terms of energy consumption and scalability.Accepted author manuscriptComputer EngineeringQuantum & Computer Engineerin
Surfactant effect of gallium during molecular beam epitaxy of GaN on AlN(0001)
No full textWe study the adsorption of Ga on (0001) GaN surfaces by reflection high-energy electron diffraction. It is shown that a dynamically stable Ga bilayer can be formed on the GaN surface for appropriate Ga fluxes and substrate temperatures. The influence of the presence of this Ga film on the growth mode of GaN on AlN(0001) by plasma-assisted molecular-beam epitaxy is studied. It is demonstrated that under nearly stoichiometric and N-rich conditions, the GaN layer relaxes elastically during the first stages of epitaxy. At high temperatures the growth follows a Stranski-Krastanov mode, whereas at lower temperatures kinetically formed flat platelets are observed. Under Ga-rich conditions-where a Ga bilayer is rapidly formed due to excess Ga accumulating on the surface-the growth follows a Frank-van der Merwe layer-by-layer mode at any growth temperature and no initial elastic relaxation occurs. Hence, it is concluded that excess Ga acts as a surfactant, effectively suppressing both Stranski-Krastanov islanding and platelet formation. It is further demonstrated that the Stranski-Krastanov transition is in competition with elastic relaxation by platelets, and it is only observed when relaxation by platelets is inefficient. As a result, a growth mode phase diagram is outlined for the growth of GaN on AlN(0001)
Atomic-layer epitaxy of GaN quantum wells and quantum dots on (0001) AlN
No full textWe show that a dynamically stable Ga film is formed on (0001) AlN in a large range of Ga fluxes at a substrate temperature of 740 °C. This feature allows for atomic layer epitaxy (ALE) of GaN on
AlN by alternate exposure to Ga and N flux. We show that, at a growth temperature of 740 °C, one ALE cycle leads to the formation of a two-dimensional GaN layer, whereas further cycles lead to the formation of GaN quantum dots following a Stranski–Krastanov growth mode. This behavior
is confirmed by atomic force microscopy, transmission electron microscopy, and
cathodoluminescence
