Charge Transport in PEDOT:PSS and Blends
Charge transport properties and metal-insulator transition in conducting polymers de pend on doping, disorder and the complex nanomorphology. Conductivity of poly(3,4-
ethylenedioxythiophene):poly(styrene-sulfonate) ...
Collective Magnetic Phases with Pentavalent Iridates
Magnetism and magnetism-driven phenomena have always remained a central theme
of modern condensed matter physics. Conventional magnetic transition, such as para magnetic to ferromagnetic phase, involves symmetry breaking ...
Interfacial - Dzyaloshinskii - Moriya interaction in quasi-perpendicularly magnetized Ta/Pt/CoFeB/Pt ultra-thin films
The physics of Ferromagnetic-Metal/Heavy-Metal(FM/HM) ultra-thin film heterostructures is not only rich enough to investigate the interplay of magnetic interactions but also relevant enough to harness a new paradigm of ...
Role of Oxygen Vacancies in Modification of Electronic Structure of Bulk Oxides
Emergent phenomena in oxides have been receiving a lot of experimental and theoretical interest in the recent decade. In general, oxides host a rich diversity of defects and several new emergent phenomena such as 2-DEG ...
Investigation of inter-layer charge transfer process in optically excited graphene and transition metal dichalcogenide-based heterostructures
Light-matter interaction of two-dimensional (2D) materials and their van der Waals hybrids have gained significant interest in the past few years as they offer an intriguing platform for studying fundamental physical ...
Electro-optic charge transport in semiconducting polymers
In this thesis, I have discussed the electric field dependence of photoconductivity of regioregular poly(3-hexylthiophene) [rr-P3HT] and its sensitization with Squaraine (SQ) dye. Even 1 wt % of SQ dye enhances the transport ...
Chaos, entanglement, and non-equilibrium dynamics in Hermitian and non-Hermitian quantum many-body systems
Quantum chaos and entanglement have appeared as two key intertwined concepts to characterize fundamental quantum correlations of quantum many-body states and to understand the emergence of thermal and non-thermal steady ...
The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
The Cahn-Hilliard-Navier-Stokes (CHNS) framework has found extensive applications, across diverse length and time scales, for multi-phase flows. In this thesis, we demonstrate that this framework offers a robust theoretical ...
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 ...
Realization of Type-II Dirac Semi-metal in NiTe2 using Structural, Electrical and Magnetic Investigation
Dirac semimetal (DSM) is a topological semi-metal with a fourfold degenerate linear
band crossing in the bulk, in the presence of time-reversal symmetry and inversion symme-
try, exhibiting nontrivial spin-momentum locking ...
