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 ...

Understanding charge transport in molecular systems is of fundamental interest in rapidly growing field of molecular electronics as well as to understand biological signal transfer processes which are accompanied by the ...

Nano-photonics deals with different ways to control light-matter interactions beyond the diffraction limit. In contrast to optics, which is the concept of light rays, including absorption, transmission, and reflection, ...

Topological classifi cation of topological insulator superconductor, various quantum Hall states are probably the most discussed topic in theoretical quantum condensed matter community as well as many mathematicians ...

Ferrites have attracted the attention of scientists and engineers in the last few years because of a combination of ferrimagnetic and insulating character. This makes them suitable for high frequency devices in telecommunication ...

The large variety of phenomena exhibited by the interface between two band-insulators LaAlO3 and SrTiO3 has attracted intense research activity in recent years.The interplay of different symmetries, viz. point group ...

Helium is an inert element with fully occupied orbitals and is a super fluid at low temperatures. An electron close to the surface of liquid Helium faces a long range attraction due to the finite polarizability of the ...

The discovery of graphene has revolutionized the field of mesoscopic condensed matter physics. It has started a new field of van-der Waals heterostructure in which different two-dimensional materials including graphene can ...

Three dimensional topological insulators are materials characterized by a gapped insulating bulk and gapless metallic states on the sample surface. This unique be- havior arises out of the non-trivial topology of the ...

Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ...
