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 ...
Electrical transport and noise in polycrystalline 2D van der Waals materials and their grain boundaries
The successful exfoliation of graphene in 2004 ushered in the era of 2D van der Waals materials, paving the way for a wide variety of applications in the field of electronics, optoelectronics, sensors, catalysis, flexible ...
Dielectric, Mechanical, Magnetic and Electromagnetic Shielding properties of Carbon nanomaterial embedded Polydimethylsiloxane composites
Composites are the advanced engineering materials invented by men with exceptional properties over traditional materials. These attractive and delightful materials are the result of developments in the area of engineering ...
Experimental Studies in Quantum Optics using Diode Lasers
This thesis discusses experimental studies with vapor cells containing rubidium (Rb) or
cesium (Cs) atoms. Transitions in the atoms (D1 and D2 lines) are accessed using diode
lasers. Experiments are performed at room ...
Structural Studies on Hybrid Peptides : Crystallographic Characterization of Sequences Containing Backbone Homologated, Monosubstituted, Unconstrained Gamma Amino Acid Residues
X-ray crystallographic studies of designed peptides provide definitive proof of the success of a design strategy and yield essential structural information that can be utilized in the future design of biologically and ...
Mesoscopic Heat engines beyond the Limits of Thermodynamics
Despite the central role that Equilibrium thermodynamics has played in our understanding of many body systems, the underlying theoretical construct is strictly correct only in the ‘Thermodynamic Limit’. On the other hand, ...
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 ...
