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 ...
Growth and Physical Properties of Biaxial Nonlinear Optical Crystals of Ascorbic Acid Family
(2018-02-26)
Saccharides, a class of organic materials, are potential candidates for nonlinear optical applications. Ascorbic acid is a sugar acid and is classified as a monosaccharide. The molecule of ascorbic acid has two chiral centers ...
Electron Filed Emission Studies of Nanostructured Carbon Materials
(2018-03-08)
Field emission is the emission of electrons from a solid under an intense electric field, of the order of 109 V/m. Emission occurs by the quantum mechanical tunneling of electrons through a potential barrier to vacuum. ...
Optical And Structural Investigations Of Defects In CdZnTe(Zn ~ 4%) Crystals
(2013-06-12)
The CdTe family members (in particular CdZnTe) remain the substrate of choice for epitaxial growth of HgCdTe for use in high performance infrared (IR) detectors and focal plane arrays. This is the case despite advances in ...
Probing Magnetic And Structural Properties Of Metallic Nanowires Using Resistivity Noise
(2013-07-19)
The main focus of this thesis work has been the study of domain wall (DW) dynamics in disordered cylindrical nanomagnets. The study attempts to accurately quantify the stochasticity associated with driven (temperature/magnetic ...
Conformation And Charge Transpsort In Conducting Polymers, Carbon Nanotubes And Their Nanocomposites
(2013-05-02)
The main motivation in this thesis is to compare the conformation and charge transport in conducting polymers and carbon nanotubes (CNTs) and to investigate those physical properties in their combined form of nanocomposites. ...
Magnetic And Transport Studies On Nanosystems Of Doped Rare Earth Manganites And VPP PEDOT
(2013-06-10)
The study of novel properties of materials in nanometer length scales has been
an extensive area of research in the recent past. The field of nanosciece and
nanotechnology deals with such studies and has gained tremendous ...
Nonequilibrium Fluctuations In Sedimenting And Self-Propelled Systems
(2013-06-10)
Equilibrium statistical mechanics has a remarkable property: the steady state probability distribution can be calculated by a procedure independent of the detailed dynamics of the system under consideration. The partition ...
Photo And Thermal Induced Studies On Sb/As2S3 Multilayered And (As2S3)1-xSbx Thin Films
(2013-05-31)
Chalcogenide glasses have attracted considerable attention due to their infrared
transparency, low phonon energy, and high non linear optical properties. They have been
explored as promising candidate for optical memories, ...
