Taming Electrons in 2D Materials: Influence of Substrates, Defects and Moire Superlattices
Two-dimensional materials have been extensively studied in the last decade owing to the rich physics at reduced dimensions and their applications in electronics and optoelectronics. Controlled modifi cation of electronic ... -
Temperature profiles and spectra of accretion disks around rapidly rotating neutron stars
In this chapter, we have computed the observed radiation spectrum from accretion disks around rapidly rotating neutron stars using fully general relativistic disk models. This is the first time such a calculation has been ... -
Tenfold Classification for Interacting Fermions and Relation with Homogeneous Spaces
Topological classifi cation of topological insulator superconductor, various quantum Hall states are probably the most discussed topic in theoretical quantum condensed matter community as well as many mathematicians ... -
The compressible ion studies on ionic solids, ionic melts and solified gases
In this chapter, the compressible?ion theory of repulsion has been applied to the alkaline?earth chalcogenides using a simplified formulation of the polyhedral cell approach. The theory correctly predicts that most of these ... -
The influence of pulsars on supernova remnants
Both Supernova Remnants (SNRs) and pulsars are products of supernova explosions; so it is natural to expect an association between them. Since various selection effects work against the detection of pulsars, the best way ... -
Theoretical and experimental studies on open circuit voltage decay lifetime and series resistance in solar cells and other P-N junction devices
Open-Circuit Voltage Decay (OCVD) is a simple and widely used technique for determining the minority carrier lifetime (??) in p–n junction devices. In this work, theoretical expressions for both Forward Current-Induced ... -
Theoretical Investigation Of Relativistic Effects In Heavy Atoms And Polar Molecules
(2009-03-20)Extensive theoretical studies on the ground and excited state properties of systems containing heavy atoms have shown that accurate prediction of transition energies and related properties requires the incorporation of ... -
Theoretical Investigations Of Core-Level Spectroscopies In Strongly Correlated Systems
(2009-03-11)Ever since the discovery of exotic phenomena like high temperature (Tc) superconductivity in the cuprates and colossal magnetoresistance in the manganites, strongly correlated electron systems have become the center of ... -
Theoretical studies on impurity models of mixed valent systems
In the first part of this thesis, consisting of the first 3 chapters, calculations of thermodynamic properties like susceptibility, magnetisation and specific heat, and of the single particle spectral density are discussed, ... -
Theoretical studies on some classical and quantum transport problems in random media
The problem of transport of charge (electrons, holes and ions) and energy (excitons) in a dynamically disordered medium is assuming increasing significance in recent times, from theoretical and experimental viewpoints. ... -
Theoretical study of quantum ohmic transport and resistance fluctuation in disordered conductors.

Theoretical Study Of Some Transport And Spectroscopic Phenomena In Two Materials Showing Large Magnetoresistance
(2009-07-09)In this thesis I present studies of some transport and spectroscopic properties for two di erent materials exhibiting large magnetoresistance. Both of these materials are oxides of transition metals, showing exotic magnetic ... -
A Theoretical Study of Thermoelectric Effect for Cross-plane Transport Across Twisted Bilayer Graphene
The thermoelectric effect and the linear response theory is one of the most studied areas in condensed matter physics. In the last few years, the study of Van Der Waals heterostructure has become one of the most promising ... -
Theoretical study on localization and transport in disordered systems
It is hard to conclude and give constructive critical remarks on a subject, especially at a stage when all the “easy” things have been done and the “hard” things left untouched. As mentioned in the Introduction, what is ... -
Thermal And Optical Properties Of Ge-Se Glass Matrix Doped With Te, Bi And Pb
(2007-12-29)During the last few years the scientific interest in chalcogenides glasses has been provoked on account of their properties and new application possibilities. These materials exhibit electrical and optical properties, which ... -
Thermal Fluctuation Spectroscopy And Its Application In The Study Of Biomolecules
(2009-03-03)The aim of this thesis is to study the energy fluctuations (leading to thermal fluctuations) during thermal and enzymatic denaturation of biological molecules and to study the variation in fluctuations between simple ...
