Study of Metal and Oxide based Synaptic Transistors by Ionic liquid Gating for Neuromorphic Computing
Neuromorphic Computing (NC), which emulates neural activities of the human brain, is considered for low-power implementation of artificial intelligence. Towards realizing NC, fabrication, and investigations of synaptic ... -
Study of Optical Properties of Semiconductor Quantum Dot Based Hybrid Nano Assemblies
(2017-11-28)Over the last few decades, a vast research is going on, to study the optical properties of the nano particles i.e., metal and semiconductors thoroughly. Till date most of the optical studies are based on single particle ... -
Study of Optimal Control Problems in a Domain with Rugose Boundary and Homogenization
(2017-12-10)Mathematical theory of partial differential equations (PDEs) is a pretty old classical area with wide range of applications to almost every branch of science and engineering. With the advanced development of functional ... -
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, ... -
Study of Phase Transitions in Two Dimensions using Electrical Noise
(2017-11-21)It is well known from Mermin-Wagner theorem that a two dimensional(2D) system with continuous symmetry can have no long-range order at finite temperature. However such systems can undergo a transition from a low temperature ... -
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 ... -
Study of room temperature coupling of colloidal quantum dots to plasmonic arrays and metamaterials: from single quantum dot to quantum dot assemblies
There is much current interest in coupling emitters, such as fluorescing dye molecules and semiconductor quantum dots to plasmonic systems. Controlling the electromagnetic interactions between quantum emitters and the ... -
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 ... -
A Study of Some Conformal Metrics and Invariants on Planar Domains
The main aim of this thesis is to explain the behaviour of some conformal metrics and invariants near a smooth boundary point of a domain in the complex plane. We will be interested in the invariants associated to the ... -
Study of Stellar Relics from the Early Galaxy
The thesis, in general aims at studying the early history of the Milky way through the chemical abundances of metal poor stars in the Halo and in the satellite galaxies of the Milky way. Halo of a galaxy is one of the early ... -
Study of Structure and Dynamics of Bioactive Natural and Synthetic Peptides by NMR Spectroscopy and In silico Methods.
The thesis covers conformational analysis of several bioactive peptides using solution and solid-state NMR along with in silico analysis of some of them compiled in five chapters. It starts with an introduction to solution ... -
Study of Subharmonic Oscillations In Resonance Excitation Experiments In Nonlinear Paul Traps
(2009-07-08)This thesis presents the results of studies on the problem of subharmonic oscillations in nonlinear Paul trap mass spectrometry. The objective of this thesis is to determine whether the subharmonic oscillations of ions in ... -
A Study of Superbubbles in the ISM : Break-Out, Escape of LYC Photons and Molecule Formation
(2018-02-16)Multiple coherent supernova explosions (SNe) in an OB association can produce a strong shock that moves through the interstellar medium (ISM). These shocks fronts carve out hot and tenuous regions in the ISM known as ... -
Study of the Effect of Ag-Addition and Double Substitution (Te/Gd and Se) on the Thermoelectric Properties of Cu12Sb4S13 Tetrahedrite
Non-renewable energy sources, such as natural gas, coal, and oil, supply over 80% of the world’s energy demands. The earth’s atmosphere is heavily polluted with CO2 generated from fossil fuels and natural gases, raising ... -
A study of the evolution of the bulges and disks of spiral galaxies in interacting and isolated environments
Galaxies are usually found in groups and clusters where they interact with each other gravitationally. These interactions affect the internal dynamics of the galaxies. In this thesis, we have studied the effect of flyby ... -
A Study of the Low-Energy Spectrum and Phase Structure of a Yang-Mills Matrix Model
Yang-Mills theory is a non-Abelian gauge theory based on the gauge group SU(N), and lies at the heart of the QCD, the theory underlying strong interactions. Due to the fundamental property of asymptotic freedom, a study ... -
A Study Of The Metric Induced By The Robin Function
(2013-09-13)Let D be a smoothly bounded domain in Cn , n> 1. For each point p _ D, we have the Green function G(z, p) associated to the standard sum-of-squares Laplacian Δ with pole at p and the Robin constant __ Λ(p) = lim G(z, p) ... -
Study of the Thermoelectric Properties of RxCo4Sb12 (R=In, Ba) with InSb/GaSb Nano Inclusions
Almost 80% of the world’s energy needs depend on oil, coal and natural gases. Use of natural gases, fossil fuels emit a large amount of CO2 to the earth’s atmosphere, which causes the greenhouse effect and results in an ... -
A Study of the X-ray Variability and Accretion Mechanism in High Mass X-ray Binary Pulsars
