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, ...
Investigating Systematics In The Cosmological Data And Possible Departures From Cosmological Principle
(2013-06-11)
This thesis contributes to the field of dark energy and observational cosmology. We have investigated possible direction dependent systematic signal and non-Gaussian features in the supernovae (SNe) Type Ia data. To detect ...
Stability of Accretion Flows And Radiative-Hydrodynamics Around Rotating Black Holes
(2013-06-24)
In the case of cold accretion disk, coupling between charge neutral gas and magnetic field is too weak such that the magneto-rotational instability will be less effective or even stop working. In such a situation it is of ...
