    Emerging Trends in Applications of Antimonide Semiconductor Alloys in Wireless Communications

    By Alla Srivani, Vedam Rama Murthy, G. Veeraraghavaiah

    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 …

    Emerging Trends in Applications of Semiconductor Alloys in Wireless Communications

    By Alla Srivani, Vedam Rama Murthy, G. Veeraraghavaiah

    Abstract: AbstractArsenide semiconductor alloys provide a natural means of tuning the magnitude of the forbidden gap and other material parameters so as to optimise and widen the application of semiconductor devices. With the advent of small-structure systems, for instance quantum wells and superlattices, the special effects of alloy composition, size, device geometry, doping and controlled lattice strain can be collective to accomplish maximum tunability. In this article, the concepts and ideas …
