Metal-assisted chemical etching of β-gallium oxide
Full text linkβ-Ga2O3, with an ultra-wide bandgap (UWB) of ~ 4.6 – 4.9 eV and bulk substrate availability, has drawn enormous interest in the power electronics community. Fabricating high-aspect-ratio β-Ga2O3 3D nanostructures without surface damage is essential for next-generation power electronics. Nonetheless, dry etch typically damages the surface due to high-energy ions, while most wet etching techniques can only produce very limited aspect ratios. In this thesis, β-Ga2O3 fin arrays by inverse metal-assisted chemical etching (MacEtch), under UV light irradiation, with a high aspect ratio and excellent surface quality, are demonstrated. The strongly crystal-orientation-dependent etching behaviors are found and three kinds of vertical structures are formed after the MacEtch process. The Schottky barrier heights (SBHs) between platinum (Pt) and different MacEtch-formed β-Ga2O3 surfaces and sidewalls are found to decrease as the aspect ratio of the β-Ga2O3 structure increases. This behavior is attributed to the varying oxygen composition on the surface after MacEtch, as shown by the XPS and TEM examination. Very little hysteresis has been observed in the capacitance-voltage characteristics of the 3D Pt/ Al2O3/ β-Ga2O3 MOS capacitor structures, and the lowest interface trap density extracted from etched interfaces is only 2.73×1011cm-2-eV-1, which is comparable to that of other published values of unetched β-Ga2O3 surfaces. This confirms that MacEtch is an effective etching method for producing high quality β-Ga2O3 3D structures.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-12-01The student, Hsien-Chih Huang, accepted the attached license on 2019-12-06 at 16:24.The student, Hsien-Chih Huang, submitted this Thesis for approval on 2019-12-06 at 16:30.This Thesis was approved for publication on 2019-12-10 at 13:59.DSpace SAF Submission Ingestion Package generated from Vireo submission #14747 on 2020-02-28 at 17:23:52Made available in DSpace on 2020-03-02T22:15:15Z (GMT).

Huang Zunxian, Qing China’s Pioneer Modernist Poet
No full textQing China's Diplomat Poet
Huang Zunxian (Huang Tsun-hsien, 1848-1905) has the distinction of being Qing China's last great classical poet but is less well known as China's first modernist poet. A diplomat of strongly reformist bent, Huang served in the consulates of Japan, the United States, Great Britain and Singapore. His poetry is rich in allusions to three thousand years of Chinese literature yet also includes detail about the foreign societies he encountered and the scientific and technological transformations that were changing the world at such an astonishing rate. His postings in Meiji Tokyo, San Francisco's Chinatown, and fin-de-siècle, London provided material for poems which treat encounters with Japanese dress reform, American racism, and British Royalty. An ascent up the Eiffel Tower in an electric elevator affords an opportunity to muse upon pre-WW1 Europe's armaments build up. Huang's poetry represents the resolute engagement of a classical poet uniquely placed to respond to conditions of contemporary global modernity. His defence of Chinatown coolies inform an indignant response to U. S. Exclusion Laws while his London poems provide us with the fascinating and hitherto unexplored Chinese counterpoint to indigenous artistic responses among Anglo-American modernists, themselves undergoing radical formal experimentation by looking East

Study of lattice manipulation in 3D liquid photonic crystals and the underlying mechanisms
No full textPhotonic crystals are periodic optical nanostructures that can be used to manipulate
the motion of photons. Their extraordinary optical characteristics like photonic band
gap and Bragg resonance (analogous to the effects of semiconductors on electron
propagation) have been widely studied and applied to laser resonators, waveguides, and
solar cells.
Compared with the traditional photonic crystals which require complex and time
consuming fabrication processes, blue phase liquid crystals and associated fabrication
techniques offer a promising route to three-dimensional photonic crystals with large
size, low defect density, and high pre- and post-fabrication tunability (by heat, electric
field, and light). Like all three-dimensional photonic crystals, the optical properties (e.g.,
photonic band gap and Kerr constant) vary with crystal orientation. Although there have
been many researches exploring how these properties vary with the crystal orientation,
very few works are on the control of blue-phase photonic crystals\ue2 orientation.
In this work, we study the effects of pitch and surface alignment on the orientation
of the fabricated blue-phase photonic crystals. We have also achieved optically
patterned orientation of blue-phase photonic crystals on the micro scale
