Electrical Spin Injection and Detection Using Oxide Magnetic Material Fe3O4
Since the proposal of Datta-Das transistor, area of spin injection and detection is in the spotlight for the last decade. Intense research in this field has successfully tackled many issues like conductivity mismatch. Use ...
Solid State NMR- Development of Methods and Applications to the Study of Materials
In this chapter the application of solid state NMR techniques for the investigation
of biodegradable polymers which have wide range of applications in various fields
have been presented. Among many polymer systems poly ...
Fully Solution Processed Flash Memory
The field of advanced solution processed spin-coated electronics has rapidly expanded over the last few decades towards the development of low-cost, large area and low power consumer electronics for the design of ...
Optoelectronic Properties of Graphene Based Van-der-Waals Hybrids
Light matter interactions in atomically thin van der Waals materials have attracted significant attention in recent day [1–6]. Although the thickness does not exceed few nano-meters, such an atomically thin materials alone ...
Optical, Electrical and Photo-physical Investigations of Cd(Hg)Te Nanostructures Synthesized by Solvothermal Method
The thesis investigates the optical, photo-physical, and electrical properties of CdTe and HgCdTe nano- and micro-structures synthesized by hydrothermal/solvothermal technique. Application oriented studies like fluorescence ...
Study of Stellar Relics from the Early Galaxy
The thesis, in general aims at studying the early history of the Milky way through the chemical abundances of metal poor stars in the Halo and in the satellite galaxies of the Milky way. Halo of a galaxy is one of the early ...
AGN Feedback in Galaxy Clisters - Controlling Cooling Flows in Galaxy Clusters by Momentum-driven AGN Jets
Synopsis
According to the hierarchical structure formation model, massive structures like galaxy clusters are formed due to the gravitational collapse of initial density perturbations and their subsequent mergers. ...
Topological Insulators and Transition Metal Dichalcogenides Under Extreme Conditions : Optical Studies
This thesis presents experimental as well as theoretical studies of three dimensional topological in-sulators (TIs) and transition metal dichalcogenides (TMDs). Raman spectroscopic measurements of these systems have been ...
Emergent Phenomena from Contacts and Disorder in High Mobility Graphene
The discovery of graphene and analogous van der Waals materials offers a platform for the discovery and exploration of various novel physical phenomena. Here we study the effects of local interaction and strong localisation ...
Iridates, Black Phosphorus, Weyl and Dirac Semimetals Under Extreme Conditions : Raman Study
This thesis presents Raman studies of Sodium iridates (Na2IrO3 and Na4Ir3O8), VO2, black phosphorus, Weyl (TaAs, TaP, NbP and NbAs) and Dirac (Cd3As2) semimetals under ex-treme conditions like low temperature (upto 4K), ...
