Probing Magnetic And Structural Properties Of Metallic Nanowires Using Resistivity Noise
(2013-07-19)The main focus of this thesis work has been the study of domain wall (DW) dynamics in disordered cylindrical nanomagnets. The study attempts to accurately quantify the stochasticity associated with driven (temperature/magnetic ... -
A Study of Electrical Transport and 1 / f Noise in Topological Insulators
(2017-12-10)The recent discoveries of topological insulators (TI) has opened a new realm for study¬ing topological systems and exploring the exotic properties they offer. The in-built topological protection against direct backscattering ... -
Study of light-matter interactions in ultra-low noise graphene-based van der Waals hybrid
The vast array of optical and electrical capabilities of graphene (Gr) and analogous two dimensional (2D) van der Waals (vdW) materials have piqued scientists’ interest for long. Stacking these materials to form hybrid ... -
Study of Phase Transitions in Two Dimensions using Electrical Noise
(2017-11-21)It is well known from Mermin-Wagner theorem that a two dimensional(2D) system with continuous symmetry can have no long-range order at finite temperature. However such systems can undergo a transition from a low temperature ... -
Study of Photo-generated Charge Transport in Graphene-based Hybrid Structures
Hybrid structures involving atomic/molecular membranes from two or more layered materials are emerging as a platform for novel class of field effect transistors (FETs), p - n junctions, photo-detectors, photo-voltaic ... -
Study on optical and electrical transport properties of twisted bilayer transition metal dichalcogenides
Van der Waals (vdW) heterostructures, where dissimilar atomically thin vdW crystals are vertically assembled, have initiated a new paradigm to create flexible multifunctional devices. Despite the weak nature of vdW ... -
Tuning the electrical and thermoelectric properties of bilayer graphene by band engineering
Graphene and its two dimensional (2D) analogues have sustained the interests of the researchers for quite some time because of the rich physics they offer including many quantum phenomena and non-trivial topological ...
