Emerging Trends in Applications of Antimonide Semiconductor Alloys in Wireless Communications
Abstract: We investigate inter diffusion in Antimonide alloy hetero structures by means of bright-field transmission electron microscopy (TEM). Samples grown by metal organic molecular beam epitaxy (MOMBE) are subjected to thermal treatment under both In-rich and Sb-rich conditions. Concentration profiles of the group-III elements are determined by evaluating changes of thickness fringes of cleaved 90° wedge specimens on a nanometer scale. We present first results of our inter diffusion experiments and …

Morphological and Dielectric Relaxation Responses of Polymer Stabilized Ferroelectric Liquid Crystal Composite Films
Abstract: Polymer-stabilized ferroelectric liquid crystal (GH-PSFLC) composite films have been prepared by polymerization-induced phase separation (PIPS) process as a function of polymer concentration. Epoxy polymer was homogeneously dispersed into FLC host matrix to create fibril network in the composite films. Twisted fibril-like network was observed through polarizing optical microscope through transmission mode. Dielectric relaxation spectroscopy of these composites shows that real part of permittivity decreases with polymer concentration. Goldstone relaxation mode …
