Multi-Nuclear and Multiple-Quantum NMR in the Solid-State : Methods and Applications
(2018-01-03)
NMR spectroscopy is a very powerful technique for the characterization of structure and dynamics of a variety of systems starting from small organic molecules to large biological macromolecules. In solids, the study of ...
Investigations on Photophysical Properties of Semiconductor Quantum Dots (CdxHg1-xTe,Ag2S) and their Interactions with Graphene Oxide, Organic Polymer Composites
(2018-02-07)
The motivation of this thesis is to understand the physical properties of semiconductor quantum dots (QDs) and to get insight on the basic physics of charge separation in composites made from QDs with graphene oxide ...
Ultra Cold Fermions : Dimensional Crossovers, Synthetic Gauge Fields and Synthetic Dimensions
(2018-02-06)
Ultracold atomic systems have provided an ideal platform to study the physics of strongly interacting many body systems in an unprecedentedly controlled and clean environment. And, since fermions are the building blocks ...
Pulsed Laser Ablated Dilute Magnetic Semiconductors and Metalic Spin Valves
(2018-04-02)
Spintronics (spin based electronics) is a relatively new topic of research which is important both from the fundamental and technological point of view. In conventional electronics charge of the electron is manipulated and ...
Modelling, Fabrication and Characterization of HgCdTe Infrared Detectors for High Operating Temperatures
(2018-02-23)
In this work, we have designed, simulated, fabricated and characterized homojunction Hg1-xCdxTe detector for high operating temperature in the MWIR region. The IR photon detectors need cryogenic cooling to suppress thermal ...
Role of Excess Fe in Pristine and Substituted Fe Chalcogenide Superconductors
(2018-03-02)
Fe chalcogenides : The discovery of superconductivity in Fe based compounds trig-
gered an intense research activity in this field with significant importance given to
material synthesis. As a result, numerous materials ...
Investigations of Phase Change Memory Properties of Selenium Doped GeTe and Ge2Sb2Te5
(2018-04-05)
GeTe and Ge2Sb2Te5 alloys are potential candidates for non-volatile phase change
random access memories (PCRAM). For electrical data storage applications the materials should have stable amorphous and crystalline phases, ...
Development of a Spin-Polarized Low Energy Electron Diffraction System and Investigation on Spin-Orbit and Exchange Interactions on Ir(100) and Ultrathin Fe(100) Grown on Ir(100)
(2018-02-28)
Spin-polarized electron beam has not yet been produced from an unpolarized electron beam using Stern-Gerlach type spin filter, because of the Lorentz force and Heisenberg uncertainty principle. At present, electron spin ...
The Many Facets of Variabilities in X-ray Binaries
(2018-02-28)
More than half a decade of X-ray astronomy with various balloon borne and space orbiting X-ray instruments, have led to discoveries and detailed studies of X-ray binaries. An important property of X-ray binaries is intensity ...
A Study of Slow Modes in Keplerian Discs
(2018-02-25)
A rich variety of discs are found orbiting massive bodies in the universe. These could be accretion discs composed of gas around stellar mass compact objects fueling micro-quasar activity; protoplanetary discs, mainly ...
