ECR Assisted Deposition of Tin And Si3N4 Thin Films For Microelectronic Applications
(Indian Institute of Science, 2006-02-27)The broad theme of the present research investigation is Ion Assisted Deposition of thin films and its effect on the properties of thin films. Though this activity has been of interest to researchers for more than a decade, ... -
ECR Plasma Deposition Of Carbon - Studies On DLC Coatings And Carbon Nanotubes
(2010-10-13)Recent developments in the field of nano-structured materials for technological as well as scientific prospective are quite interesting. In this context carbon plays a dominant role. Few examples such as carbon nanotubes ... -
ECR Studies Across Bare And Gold Coated Metal Contacts At Low Temperatures
(2011-01-28)Electrical contact resistance (ECR) measurements are needed for judging the performance of electrical appliances. Understanding the behaviour of ECR at low temperature gives a unique opportunity for understanding the contact ... -
Edge States and Effects of Disorder in Finite Graphene Sheets
The thesis endeavours to theoretically understand electronic properties of nite trapezoidal shaped graphene sheets, and understand zero energy edge states. The motivation for this thesis is recent experimental work at Low ... -
Effect of a fast flux line on the coherence of 3D transmon qubits
With the development of the science and technology, the quantum computers are becoming the possible key to reveal new breakthroughs. Unlike the classical computers, where we have classical bits (0or1), in quantum computation ... -
Effect of Antimony Doping in Iron Chalcogenides
(2017-11-27)This thesis is organized in to six chapters. The contents of each chapter are briefly summarized in the following sections. Chapter 1 introduces different Fe-based superconductors. Within a very short span of their ... -
Effects Of Disorder On Physical Properties Of Selected Transition Metal Oxides
(2013-02-14)Disorder in materials often brings in new and exotic physical properties along with it. It is thus very important to study different kinds of disorder and their implications on various material properties. In this thesis, ... -
Effects Of Spin Polarization And Spatial Confinement On Optical Properties Of Bulk Semiconductors And Doped Quantum Wells
(2010-04-06)We correlated experimental results with theoretical estimations of the dielectric function ε(ω) in two contexts: the effect of an electric field in quantum wells and that of the spin polarization of an interacting electron-hole ... -
Effects of Strong Electron-Electron Correlations on Band Insulators in Equilibrium and Non-Equilibrium
In this thesis, several aspects of correlation effects in band insulators that were hitherto not addressed, both in equilibrium and non-equilibrium, are studied using the Ionic Hubbard model (IHM) at half-filling and ... -
An Efficient Quantum Algorithm and Circuit to Generate Eigenstates Of SU(2) and SU(3) Representations
(2018-04-18)Many quantum computation algorithms, and processes like measurement based quantum computing, require the initial state of the quantum computer to be an eigenstate of a specific unitary operator. Here we study how quantum ... -
Efficient Quantum Algorithms for Linear Algebra Problems
Many simulation problems can be expressed as time evolution under specific interactions, from some simple initial state to a final state whose properties are to be investigated. In this context, the Hamiltonian evolution ... -
Eigenvalues of Products of Random Matrices
(2018-02-07)In this thesis, we study the exact eigenvalue distribution of product of independent rectangular complex Gaussian matrices and also that of product of independent truncated Haar unitary matrices and inverses of truncated ... -
