Development of Graphene Based Sensors for Human Physiological Monitoring and Vacuum Measurement
Nanomaterials have emerged as a remarkable class of materials in recent years owing to their excellent electrical, chemical, and physical properties. The first two-dimensional (2D) material to be discovered, graphene, has ... -
Hyperspectral and Spectropolarimetric Instrumentation for the Solar Atmosphere
The Sun is the closest star whose surface can be resolved to great a detail. Understanding the working of Sun helps in understanding a large fraction of stellar system as it falls under the spectral class G2V which is ... -
Carbon nanomaterials for energy and environmental applications
Environmental pollution and energy storage are two important issues in the modern day society. In this regard, Carbon nanomaterials have attained immense importance, due to their high surface area and electrical conductivity ... -
Studies in Strongly Correlated Systems: From Ultracold Superfluids to Strange Metals
Almost all the technology that we use today depends on our ability to control and exploit the properties of many electron phases. These phases are primarily made up of non-interacting fermions embodied in a metal or a ... -
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 ... -
Living on the Edge A Study of Boundary Modes In Two-dimensional Topological Systems
In the last few decades an enormous amount of research has been carried out on some novel phases of matter called topological phases which are beyond the paradigm of Landau’s theory of symmetry breaking. One of the ... -
Proton kinetic energy anomaly, Kauzmann temperature for nanoconfined water and design of nanoscale membrane for water desalination.
Structure, dynamics and thermodynamics of water molecules con fined inside the nanopores of various geometries are of fundamental interest owing to their potential applications in various nanofluidic devices, such as ... -
Surface Adsorption of Dendrimers: Structure, Interactions at Graphene/Water Interface and Applications in Supercapacitors
The study of structure and dynamics of geometrically con ned polymers has been an interesting topic of research. In this thesis we speci cally studied the adsorption behavior of a hyper-branched polymer called poly(amidoamine) ... -
Implications in substrate recognition, catalysis and drug-design Structural basis for neutralization of ribosome-inactivating proteins by their monoclonal antibodies
Cryptic elements of proteins are not visible in unbound structures but become apparent in ligand/substrate-bound structures. These binary states of cryptic elements in protein structures can impact important aspects of ... -
Structural and functional studies on DNA synthesis and repair proteins
The work reported in this thesis includes structural and functional studies on thymidylate kinase and RecFOR pathway proteins from Thermus thermophilus HB8. In the first part, a study was performed on the thymidylate ... -
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 ... -
Raman Study of gated devices in two-dimensional materials and pressure effects
This thesis presents Raman study of 2D materials of contemporary interests: 2H-MoTe_2, type-II Weyl semimetal (T_d-MoTe_2), structurally anisotropic semiconductors (1T'-ReX_2 (X=S, Se)) and Mott insulator (FePS_3) under ... -
Conductance Fluctuations in High-mobility Graphene Field Effect Transistors
In the past decade, a major fraction of the research carried out in condensed matter physics has been dedicated to address the unique physical properties of single layer graphene (SLG). Different properties of Dirac ... -
Charge Transport in Molecular Systems
Understanding charge transport in molecular systems is of fundamental interest in rapidly growing field of molecular electronics as well as to understand biological signal transfer processes which are accompanied by the ... -
Applications of Holography
This thesis consists of four parts. In the first part of the thesis, we investigate the phase structure of Einstein-Maxwell-Scalar system with a negative cosmological constant. For the conformally coupled scalar, an ... -
Near Optimal Non-malleable Codes and Leakage Resilient Secret Sharing Schemes
A well-studied class of attacks on cryptosystems called "side-channel attacks", stems from the additional access that an adversary can get due to the susceptibility of the hardware on which the cryptosystem (e.g., digital ... -
Advanced Instrumentation for Detection of Defects and Diseases in Sericulture
Sericulture is the art of rearing silkworms for silk production. The matured silkworms will be spinning cocoons as a protective shield before they undergo metamorphosis. These cocoons are immersed in boiling water to soften, ... -
