TEM Study on the Evolution of Ge Nanocrystals in Si Oxide Matrix as a Function of Ge Concentration and the Si Reduction Process
(2006-01)Growth and evolution of germanium (Ge) nanocrystals embedded into a silicon oxide (SiO₂) system have been studied based on the Ge content of co-sputtered Ge-SiO₂ films using transmission electron microscopy (TEM) and X-ray ... -
A theory of amorphous polymeric solids undergoing large deformations: application to micro-indentation of poly(methyl methacrylate)
(2004-01)Although existing continuum models for the elasto-viscoplastic response of amorphous polymeric materials phenomenologically capture the large deformation response of these materials in a reasonably acceptable manner, they ... -
TiNi shape memory alloy thin films for microactuator application
(2003-01)TiNi films were prepared by co-sputtering TiNi target and a separate Ti target. Crystalline structure and phase transformation behaviors of TiNi films were investigated. Results showed that TiNi films had fine grain size ... -
TiNi-based thin films for MEMS applications
(2004-01)In this paper, some critical issues and problems in the development of TiNi thin films were discussed, including preparation and characterization considerations, residual stress and adhesion, frequency improvement, fatigue ... -
Two-dimensional Photonic Crystals Fabricated by Nanoimprint Lithography
(2005-01)We report on the process parameters of nanoimprint lithography (NIL) for the fabrication of two-dimensional (2-D) photonic crystals. The nickel mould with 2-D photonic crystal patterns covering the area up to 20mm² is ... -
Vibrational thermodynamics: coupling of chemical order and size effects
(2002-01)We study the effects of vibrations in the Pd₃ system using first-principles pseudopotential calculations. We find that upon disordering from the DO₂₂ phase, the decreases by 0.07kB. We explain our results in terms of atomic ... -
Wafer-Level Thermocompression Bonds
(2003-01)Thermocompression bonding of gold is a promising technique for achieving low temperature, wafer-level bonding without the application of an electric field or complicated pre-bond cleaning procedure. The presence of a ductile ... -
Workfunction Tuning of n-Channel MOSFETs Using Interfacial Yttrium Layer in Fully Silicided Nickel Gate
(2007-01)Continual scaling of the CMOS technology requires thinner gate dielectric to maintain high performance. However, when moving into the sub-45 nm CMOS generation, the traditional poly-Si gate approach cannot effectively ... -
ZnO Nanorods Grown on p-GaN Using Hydrothermal Synthesis and Its Optoelectronic Devices Application
(2007-01)The ZnO nanorods with the length of 1-1.5 μm were deposited on p-GaN by hydrothermal synthesis at low temperature 100°C. The structural and optical properties of the as-grown ZnO rods were investigated by X-Ray diffraction ...
