Electron Paramagnetic Resonance and Magnetic Studies of Certain Doped Rare Earth Manganites
Doped rare-earth manganites with the general formula T1xDxMnO3 where `T' is a trivalent
rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion,
e.g Ca2+; Sr2+;Ba2+ etc. display various ...
Fluctuations in quantum transport in topological insulators
Topological insulators (TIs) belong to a new class of materials characterized by linear
surface states, which emerge in the bulk band gap due to non-trivial topology of the band
structure. These surface states have various ...
Coulomb drag to thermopower response in dimensionally mismatched InAs nanowire-Graphene heterostructures and anisotropic noise in ReS2
Coulomb drag technique is a notable tool for probing electron-electron interaction in double-layer systems, where the momentum and energy transfer from one layer to the other layer as a result of Coulomb interaction. In ...
Development and Characterization of Mercury Cadmium Telluride Colloidal Quantum Dot Based Infrared Optical Sensor
Motivation of this thesis is to synthesize HgCdTe quantum dots responsive in MWIR spectral range using chemical synthesis method and develop room temperature operated
MWIR focal plane array using commercial silicon ROIC ...
Rapid light sheet fluorescence microscopy for dynamic imaging of living organisms
The primary goal of this thesis is to develop a light sheet based microscopy system
that provides non-invasive images having high spatial and temporal resolution. The
fluorescence
microscopy has become an indispensable ...
Turbulent Mixing of Multiple-Passive-Scalars
We have studied the mixing of multiple forced passive scalars in 3D homogeneous
and isotropic turbulence. The trends of the structure functions for a
single scalar, although not very well resolved, seem to be similar to ...
Electrical transport in 3-dimensional topological insulators
Topological insulators (TI) are a new class of materials in which gapped bulk states coexist with gapless surface-states having linear energy-momentum dispersion relation protected by time-reversal symmetry. These ...
Physics and application of charge transfer in van der Waals heterostructures
Since the discovery of graphene, the field of 2D materials has garnered massive interest from a materials science, basic physics and device application point of view. This
results from the diverse range of electronic and ...
A Theoretical Study of Thermoelectric Effect for Cross-plane Transport Across Twisted Bilayer Graphene
The thermoelectric effect and the linear response theory is one of the most studied areas in condensed matter physics. In the last few years, the study of Van Der Waals heterostructure has become one of the most promising ...
Dynamics and Organization of Passive and Magnetically Driven Colloids Under Optical Confinement
The physics of confined systems of interacting particles has been a subject of active research for more than a century. Such systems are ubiquitous in nature - examples include petroleum in porous rocks, cytoplasm in ...
