Growth of Semiconductor and Semiconducting Oxides Nanowires by Vacuum Evaporation Methods
(2018-04-12)Recently, there has been a growing interest in semiconductor and semiconducting oxide nanowires for applications in electronics, energy conversion, energy storage and optoelectronic devices such as field effect transistors, ... -
Growth, Structural And Physical Properties Of Certain Antimony Based III-V Diluted Magnetic Semiconductors
(2010-07-20)Semiconductor devices are the building blocks of electronics and communication technology in the modern world. The charge, mass and spin of charge carriers in the semiconductor devices lay the foundations of the technology ... -
Growth, synthesis, structure, properties and fluorination of barium bismuthate and related oxides
This thesis presents a comprehensive study on the synthesis and characterizations of bismuthates, particularly focussing on BaBiO3 and its fluorinated variants, alongside the exploration of strongly correlated oxides such ... -
Growth, Transport, Magnetic And Thermal Studies On Single Crystals Of Pr1-xPbxMnO3
(2009-06-17)Mixed valence manganites with the perovskite structure R1-xAxMnO3 (where R = La, Nd, Pr and A = Ba, Ca, Sr, Pb) have been a popular subject of contemporary research because of their interesting physical properties such as ... -
Grushin Multipliers and Toeplitz Operators
This work investigates advanced concepts in functional analysis and partial differential equations, focusing on Sobolev spaces and their weighted variants. The study explores properties of functions in Lp(Rn+1)L^p(\mathb ... -
Hand-Movement Prediction Using LFP Data
(2011-08-08)The last decade has seen a surge in the development of Brain-Machine Interfaces (BMI) as assistive neural devices for paralysis patients. Current BMI research typically involves a subject performing movements by controlling ... -
Hardy's inequalities for Grushin operator and Hermite multipliers on Modulation spaces
This thesis consists of two broad themes. First one revolves around the Hardy's inequalities for the fractional power of Grushin operator $\G$ which is chased via two different approaches. In the first approach, we first ... -
Harmonic Map Heat Flow and Framed Surface-group Representations
This thesis concerns the construction of harmonic maps from certain non-compact surfaces into hyperbolic 3-space H3 with prescribed asymptotic behavior and has two parts. The focus of the first part is when the domain ... -
Heavy flavour and direct photon probes of the gluon Sivers function
Traditionally the production of heavy quarkonia, heavy-flavour mesons as well as of direct photons, has been used to constrain the gluon density inside the proton. In this thesis, I have assessed various heavy flavour ... -
Herglotz representation, approximation by inner functions, and Hankel operators
This thesis can be broadly categorized under the theories of multi-variable operators and holomorphic functions, structured into two distinct parts. The first part investigates the relationship between two classical theorems: ... -
Hermitian Metrics and Singular Riemann Surface Foliations
The main aim of this thesis is to understand curvature properties of a given hermitian metric by restricting it to the leaves of a suitable singular Riemann surface foliation. We will specifically consider the complete ... -
The Higgs Boson as a Probe of Physics Beyond the Standard Model at the Large Hadron Collider
(2018-05-08)The nature of interactions of fundamental particles is governed by symmetries. These interactions are well described by an elegant and simple SU(3)c x SU(2)L x U(1)Y symmetric gauge theory that we call the Standard Model ... -
Higgs phenomenology and Dark Matter prospects in MSSM, NMSSM and U(1) extended SM
Particle physics today is at a juncture where all particles predicted within Standard Model (SM) have been discovered at the particle colliders while no particles from the realm of physics beyond the Standard Model (BSM) ... -
High Magnetic Field Neutron Stars : Cyclotron Lines and Polarization
(2018-04-16)This thesis concerns with the study of X-ray binaries which are gravitationally bound systems consisting of a compact object (either a neutron star or a black hole) and usually a non degenerate companion star, both rotating ... -
High Precision Optical Frequency Metrology
(2009-07-22)Precise measurements of both absolute frequencies and small frequency differences of atomic energy levels have played an important role in the development of physics. For example, high precision measurements of absolute ... -
High rydberg state recombination lines from interstellar carbon : an observational study
This thesis describes the results of an observational study of partially ionized gas in the Galaxy using low-frequency radio recombination lines of carbon, which arise due to electronic transitions at large quantum numbers ... -
High-K Dielectrics–Studies on (Ta2O5)1-x– (TiO2)x, (0 ≤ x ≤ 0.11), Thin Films
Recently the increasing demand for miniaturized electronic gadgets has raised the interest in searching the high dielectric constant (K) materials for memory elements. Among the investigated high dielectric constant metal ...
