Spintronics would utilize the spin of the electron for information processing and storage, leading to devices that may be smaller, faster, and more energy-efficient than their electronic counterparts. Before these spin-based devices can be fully realized, we must answer the foll…

High quality and accurate computational data was obtained through first principle quantum mechanical calculations originated from density functional theory without the inclusion of empirical data (ab initio). The support of the computing facility NGS allows us to carry out our r…
The research carried out here employed analytical and imaging transmission electron microscopy and scanning transmission electron microscopy to gain a good understanding of local structure and composition of semiconductor nanocrystals and quantum dots for electronics and optoele…
Experimental investigations of phase transformation scenarios and the resulting microstructures and texture of crystallization of amorphous GaAs films on SiO2 induced by excimer laser are presented. The variation of grain size as a function of the incident energy density reveals…
In this PhD. research, a new power amplifier architecture is introduced. This work develops the push-pull architecture into a multifunctional matching network and combiner to create a high power, high efficiency, linear power amplifier (PA) that operates over a wide bandwidth. T…
Amplifiers in the final stages of wireless transmitters boost the power level of the up-converted signals. Unfortunately, the ultimate power level is not the same for all transmitters. This same amplifier can be used as a driver in cellular base stations or as the last stage in …
Nanostructures have become an important field of study in the past few years for their interesting physical characteristics due to features' size and quantum confinement, which have added new potential applications to the scope of electrical and optical devices. Quantum dots (QD…
