Optical Properties of Sb2Te3, and Dilute Magnetic Semiconductors Sb1.97 VO.03 Te3 and Sb1.94 CrO.06 Te3
This thesis reports on the optical properties of the dilute magnetic semiconductors, Sb1.97 V 0.03 Te3 and Sb1.94Cr0.06Te3, along with the parent compound Sb2Te3' These materials develop a ferromagnetic state at low ...
Infrared Spectroscopy of Gadolinium
Measurements of the optical reflectivity of the normal incident light along c-axis  have been made on a Gadolinium single crystal, for temperatures between 50 K and room temperature just above the Curie temperature ...
Generalization of the BTK Theory to the Case of Finite Quasiparticle Lifetimes
(Brock University, 2013-01-24)
A generalization to the BTK theory is developed based on the fact that the quasiparticle lifetime is finite as a result of the damping caused by the interactions. For this purpose, appropriate self-energy expressions and ...
Planar Topological Defects in Unconventional Superconductors
(Brock University, 2013-09-12)
In this work, we consider the properties of planar topological defects in unconventional superconductors. Specifically, we calculate microscopically the interaction energy of domain walls separating degenerate ground ...
