Interplay between the Mechanics of Flexible Substrates and Performance of Thin Film Transistors: Role of Buckled Geometry
Buckled Thin Film Transistor (TFT) resulting from the stress induced instability of thin films realized on a exible substrate can behave di erently than that of a planar device. The aim of this thesis is twofold: To ... -
Interplay of disorder and superconductivity in ultra-thin Sn films
This thesis reports low-temperature, in-situ transport measurements on quench-condensed ultra-thin films of Sn. Film thicknesses are < 100 Å. These films exhibit an insulator-to-superconductor transition. Novel effects are ... -
Interplay of Electrons and Phonons in 2D Materials
Since the seminal study by Cao et al. in 2018, that revealed the emergence of superconductivity and correlated insulating behaviour in twisted bilayer graphene (TBG), there has been a surge of exciting discoveries in moiré ... -
Interplay of Interaction and Topology From Topological Band Theory to Topological Field Theory
Classification of phases of matter has long been a central point of interest in the research community in condensed matter physics. Over the past several decades mainly two kinds of classification schemes have emerged, ... -
An Introduction to Minimal Surfaces
(2017-12-10)In the first chapter of this report, our aim is to introduce harmonic maps between Riemann surfaces using the Energy integral of a map. Once we have the desired prerequisites, we move on to show how to continuously deform ... -
Invariants Associated with Complete Nevanlinna-Pick Spaces
The broad aim of this thesis is to study certain tuples of bounded operators that satisfy an operator inequality arising from a complete Nevanlinna-Pick kernel. Specifically, we focus on two invariants of these operator ... -
Investigating Magnetic Transitions and the Quantum Spin Liquid State in Complex Oxides
Magnetic properties emerge from the interplay of spin, crystal structures, and external factors such as temperature, magnetic fields, and pressure, resulting in a diverse range of magnetic phenomena with potential applications ... -
Investigating Nucleosynthesis During Formation of Black Holes and Extracting Their Properties
Measurement of black hole spins is of great interest to physicists in general and to astrophysicists in particular, as this provides a direct proof of the theory of general relativity for rotating black holes. It involves ... -
Investigating spin transport across magnetic insulators and their interfaces
Spin transport across magnetic insulator/heavy metal (MI/HM) interfaces has been a topic of interest in spintronics. The spin Seebeck effect (SSE) and spin Hall magnetoresistance (SMR) are two phenomena that have ... -
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 ... -
Investigation into flux-coupled electromechanical devices
Cavity optomechanical systems involve modulation of the resonance frequency of an optical cavity by the motion of a mechanical resonator. These systems are used to control and manipulate mechanical motion down to the quantum ... -
Investigation Of Damage Process In Current Stressed Metal Film Using Noise Spectroscopy, Scanning Thermal Microscopy And Simulation Studies
(2010-09-27)Reliability, besides the performance, is one of the important key factors of success of any technology. While a product should perform at best as desired, it must also be capable of working for intended period of life ... -
