Emergent Phenomena from Contacts and Disorder in High Mobility Graphene
The discovery of graphene and analogous van der Waals materials offers a platform for the discovery and exploration of various novel physical phenomena. Here we study the effects of local interaction and strong localisation ...
Study of Photo-generated Charge Transport in Graphene-based Hybrid Structures
Hybrid structures involving atomic/molecular membranes from two or more layered materials
are emerging as a platform for novel class of field effect transistors (FETs), p - n
junctions, photo-detectors, photo-voltaic ...
Tuning the electrical and thermoelectric properties of bilayer graphene by band engineering
Graphene and its two dimensional (2D) analogues have sustained the interests of the
researchers for quite some time because of the rich physics they offer including many
quantum phenomena and non-trivial topological ...
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, ...
Ultrafast Photoexcited Carrier Dynamics in Low Dimensional Systems Probed by Time Resolved Terahertz Spectroscopy
The key aspect of this thesis is to understand the photoinduced carrier dynamics in low dimensional systems by employing time resolved optical pump-terahertz probe (OPTP) spectroscopy. Ultrafast pulsed laser (Ti: Sapphire ...
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 ...
Statistics of Conductance Fluctuations in 2D systems
Study of 2D materials is interesting due to the various phase transitions observed
in these materials. I shall present the results obtained in the study of phase transi tions in three different 2D material systems – ...
Investigation of inter-layer charge transfer process in optically excited graphene and transition metal dichalcogenide-based heterostructures
Light-matter interaction of two-dimensional (2D) materials and their van der Waals hybrids have gained significant interest in the past few years as they offer an intriguing platform for studying fundamental physical ...
