The accurate value of thermal expansion coefficient ( ) of thin film is an important thermal property in the design of microelectronic devices and microsystem. This research presents a microbridge buckling deformation caused by the residual stresses to determine the of thermal oxide (SiO2) film. The extraction of is supported through experimental means and finite element analysis (FEM) of the b...
For the thickness 0 5 a liquid or solid quantum f i lm, like liquid helium or solid hydrogen, there exist still open questions about how the film thickness develops in certain limits. One of these is the thick film limit, i.e., the crossover from the thick film to bulk. We have performed rneasurements in this range using the surface plasmon resonance technique and an evaporated h g film deposit...
We report a high-spatial resolution imaging technique to measure optical absorption and detect chemical and physical changes on surfaces embedded in thick tissue. Developing sensors to measure chemical concentrations on implanted surfaces through tissue is an important challenge for analytical chemistry and biomedical imaging. Tissue scattering dramatically reduces the resolution of optical ima...
in this paper electrical conductivity measurements and optical investigations takes place in aot/ heptane/ (water or aqueous) systems. the water in oil system prepared with adding water in 50% by weight of aot/ heptane solution. in other systems instead of water, aqueous solutions of 1) zinc acetate and water 2) potassium hydroxide and water were used. in each phase, the trend of the electrica...
We had accomplished recording and readout of bit patterns by two-photon 3D optical storage technology using a new photochromic diarylethene, 1,2-bis(2-methyl-5-methylene-n-butylamido-thien-3-yl) perfluorocyclopentene (BMMBTP), as memory medium. The photochromic reaction, both in solution and in poly(methyl methacrylate) (PMMA) amorphous film, and fluorescence property of BMMBTP were investigate...
We investigate the interfacial phase behavior of a binary fluid mixture composed of repulsive point Yukawa particles. Using a simple approximation for the Helmholtz free energy functional, which yields the random phase approximation for the pair direct correlation functions, we calculate the equilibrium fluid density profiles of the two species of particles adsorbed at a planar wall. We show th...
Vertically aligned single-walled carbon nanotubes (SWNTs) up to 5 microns thick as shown in Fig 1 were produced by an alcohol CVD process [1]. In contrast to the first report of CVD growth of vertically aligned SWNTs [2], hydrogen gas was supplied only during the heating-up stage with the improved background vacuum condition. A time-progressive investigation of the growth process was studied by...
CTS began manufacturing pointing devices in 1994 for use as cursor controls, mounted in the keyboards of notebook computers. While completed keyboards were robust against ESD, many precautions were required during manufacture and assembly to protect against the effects of ESD. While these ESD “protective” controls were effective in controlling ESD, they did not eliminate the ESD susceptibility ...
