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) ...
Linear Nanopositioning Systems for Scanning Probe Microscopy
Scanning probe microscopes (SPM) are vital for visualizing and characterizing samples of interest to various fields with nanometer resolution, such as semiconductor fabrication, microbiology, and material engineering. The ...
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 ...
Studies of Feynman and Related Integrals and their Hypergeometric Connection using the Method of Brackets, Algebraic Relations and Singularity Analysis
Feynman integrals are special kind of integrals that arise in perturbative quantum field theory and are often very difficult to evaluate in terms of known functions of mathematical physics. At times some of the methods ...
Insights into the genesis and dynamics of the solar spicule forest: aided by simulations and laboratory experiments
The solar atmosphere is embedded with an enormous no of plasma structures with a vast range
of spatial and temporal scales. Solar spicules are one of such ubiquitous features of the sun,
which are present in millions ...
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ...
Feynman Integral Calculus and Hypergeometric Functions: New Results, Interconnections and Computer Algebra
Feynman integrals play a fundamental role in perturbative calculations within the realm of quantum field theory. In this thesis, we study several important mathematical properties of multi-loop multi-leg Feynman Integrals ...
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 ...
