Design of new logic architectures utilizing optimized suspended-gate single-electron transistors
No full textThe operation and performances of the suspended-gate single-electron transistor (SET) are investigated through simulation. The movable gate is 3-D optimized, so that low actuation voltage (0.4 V), fast switching (1 ns), and ultralow pull-in energy (0.015 fJ) are simulated. A two-state capacitor model based on the 3-D results is then embedded with a SET analytical model in a SPICE environment to investigate the operation of the device. Through the control of the Coulomb oscillation characteristics, the position of the movable gate enables a background charge insensitive coding of the information. New circuit architectures with applications in cellular nonlinear network and pattern matching are also proposed and simulated
Control of inter-dot electrostatic coupling in an asymmetric silicon double quantum dot operating at 4.5 K
No full textWe report on electron transport measurements of a lithographically-defined silicon double quantum dot (DQD) coupled in series with a top gate and side gates. The structure of the top gate coupled uniformly to the DQD is suitable for realizing a few-electron regime. The obtained small DQD enables us to observe a clear honeycomb-like charge stability diagram at a temperature of 4.5 K. The validity of the DQD structure is confirmed by theoretical calculations. Furthermore, we demonstrate successful modulation of the inter-dot electrostatic coupling by the side gate. Externally tunable coupling is essential for practical implementation of spin-based quantum information devices

Stylodes absent. Mouth palps absent, but a spiral projection for brood attachment originates from the right side of the mouth. Collar non-lobed, tonguelets absent. Thoracic membranes narrowing at third chaetiger but continuing to 7 th thoracic chaetiger, a narrow apron is probably present. Seven thoracic chaetigerous segments. Collar chaetae limbate. Apomatus chaetae absent. Thoracic uncini of Protis type, sawshaped with about 10 teeth, anterior fang with pointed tip. Thoracic triangular depression not observed. Anterior abdominal chaetae flat narrow geniculate with a row of sharp teeth along its free margin. Abdominal uncini similar to thoracic ones but rasp-shaped. Achaetous anterior abdominal zone present, short (2–4 segments). Long posterior capillary chaetae present. Posterior glandular pad not observed. Remarks. The genus currently includes two species P. dendrova and P. pu l c h r a (the latter generic attribution questionable), however, our preliminary molecular data (Kupriyanova et al. unpubl.) indicate that these two species are not closely related, thus, P. pulchra should be transferred to another genus.Published as part of Kupriyanova, Elena K., Sun, Yanan, Ten Hove, Harry A., Wong, Eunice & Rouse, Greg W., 2015, Serpulidae (Annelida) of Lizard Island, Great Barrier Reef, Australia, pp. 275-353 in Zootaxa 4019 (1) on pages 300-301, DOI: 10.11646/zootaxa.4019.1.13, http://zenodo.org/record/28949

TM-scattering from notches in a parallel-plate waveguide
No full textThe problem of TM-mode scattering from the finite number of rectangular notches in a parallel plate waveguide is considered. The Fourier-transform is employed to obtain simultaneous equations and the simultaneous equations are solved to obtain an analytic solution in rapidly-convergent series. Numerical computations are performed to investigate the scattering behavior in terms of frequency and notch sizes. The presented theory is applicable to the analysis of scattering from the E-plane stubs in the rectangular waveguide
