THERMAL CONDUCTIVITY OF THIN FILM NIOBIUM DISELENIDE FROM TEMPERATURE-DEPENDENT RAMAN
Niobium diselenide (NbSe2) possess a high electrical conductivity and low thermal conductivity, making it a candidate for thermoelectric devices. While the electronic properties of (NbSe2) has been relatively explored, the lateral thermal conductivity for (NbSe2) has remained unknown. In this …

SPIN AND CHARGE TRANSPORT IN 2D MATERIALS AND VAN DER WAALS HETEROSTRUCTURES
… Preliminary results on a Ising superconductor NbSe2 are presented. Firstly, 2D superconductivity in ultra-thin NbSe2 is verified by fluctuation effects, square root dependence of in-plane upper critical field as well as BKT transition. Secondly, spin-polarized tunnel spectroscopy of NbSe2 is …

Scanning tunneling microscopy and spectroscopy study of layered transition metal chalcogenide thin films tuned by thickness, structural phase, and heterostructure
… same phase engineering strategy was adopted for NbSe2 growth. While monolayer 1H-NbSe2 is demonstrated to host unconventional superconductivity, the Mott insulating ground state and strong evidence for the presence of spinon Fermi surface are disclosed in metastable 1T-NbSe2 monolayers. Besides, …

A nanoscale probe of the quasiparticle band structure for two dimensional electron systems
… wave (CDW) order in the dichalcogenide 2H-NbSe2 - a model system for understanding the interplay of coexisting CDW and superconducting phases. We detail the observation of a previously unknown unidirectional (stripe) CDW smoothly interfacing with the familiar triangular CDW on this …

Optics and Optoelectronics of Atomically Thin Magnets and Semiconductors
… such as MoS2 and superconductors (ie NbSe2) to name a few. These materials are of significant fundamental interest, since they offer the first opportunity to study physical phenomena in a truly two-dimensional system, while showing layer-dependent emergent properties unavailable in any …

Point-contact Andreev reflection studies on superconductors
Point-contact Andreev reflection spectroscopy (PCARS) and planar tunneling spectroscopy are used to investigate the density of states and superconducting gap structure of several novel superconducting systems. Theoretical and experimental background is given with an emphasis on PCARS as applied to …
