Studies of Diamagnetism and Thermoelectric Transport in High Temperature Superconductors and Graphene
Using a recently proposed Ginzburg-Landau-like free energy functional due to Banerjee et al. Phys. Rev. B 83, 024510 (2011) we calculate the fluctuation diamagnetism of high-T c superconductors as a function of doping, ...
Study of Optoelectronic Properties of Quantum Emitter Assemblies Coupled to Graphene, Photonic and Plasmonic Materials
Nano-photonics deals with different ways to control light-matter interactions beyond the diffraction limit. In contrast to optics, which is the concept of light rays, including absorption, transmission, and reflection, ...
Edge States and Effects of Disorder in Finite Graphene Sheets
The thesis endeavours to theoretically understand electronic properties of nite trapezoidal shaped graphene sheets, and understand zero energy edge states. The motivation for this thesis is recent experimental work at Low ...
