Raman Studies of Topological Crystalline Insulator, Natural Heterostructures, Excitonic Insulator and Layered Oxide Under Pressure
The theme of this thesis is Raman spectroscopic study of a variety of exotic states of matter under extreme conditions, such as, hydrostatic pressure as high as 25 GPa and a wide temperature range from 77 K to 390 K. Raman ...
Raman Study of gated devices in two-dimensional materials and pressure effects
This thesis presents Raman study of 2D materials of contemporary interests: 2H-MoTe_2, type-II Weyl semimetal (T_d-MoTe_2), structurally anisotropic semiconductors (1T'-ReX_2 (X=S, Se)) and Mott insulator (FePS_3) under ...
Impact of van der Waals epitaxy on structural and optoelectronic properties of layered solids
Emergence of Graphene, Transition metal dichalcogenides (TMDCs) and other van
der Waals materials promises to rede fine the building blocks of the future materials and
technologies. These materials have gained enormous ...
Phonon anomalies in pyrochlores and 2D materials under extreme conditions: Insights from Raman spectroscopic studies
In solids, electrons do not behave as separate particles but instead interact intensely
to form quasiparticles, which couple with other quasiparticles such as phonon,
plasmon, and exciton to generate emergent quantum ...
