condensation

In this thesis we have studied phase transitions in a polymer solution and also in a two dimensional (2D) disordered system. In our study on the polymer system we present a model in an attempt to understand the observed crossover of a stiff polymer chain with side groups in a so…

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…

ZnO thin films were prepared by using the DC Reactive Magnetron Sputtering technique. The effect of the working pressure, substrate temperature, Fe-doping, and oxygen concentration in the gas ambient on the structural, optical and electrical properties of the grown films were st…

The objective of this research was to develop an atomistic, first principles-based approach for the study of dilute magnetic semiconductor (DMS) materials at the nano scale, focusing on the goal of predicting the extent of magnetoresistance. DMS materials are those semiconductor…

First-principles calculations for the electronic and geometric structures of three different types of armchair and zigzag silicon carbide nanotubes from (3, 3) to (11, 11) and (3, 0) to (11, 0) have been performed using hybrid density functional theory and the finite cluster app…
