Observation of Intrinsic Anderson Localization in Few-Layer ReS
Shreya Paul, Pritam Das, Devarshi Chakrabarty +2
Electron localization phenomena are expected to play an important role in the transport properties of two-dimensional materials. Rhenium disulfide (ReS), with its narrow conduc…
Probing spin dynamics of 2D excitons with twisted light
A. K. Pattanayak, P. Das, D. Chakrabarty +5
We propose a mechanism of intravalley spin-flip scattering in spin-valley coupled two dimensional systems by transferring momentum of light into exciton center of mass using optica…
A steady state approach for studying valley relaxation using optical vortex beam
Aswini Kumar Pattanayak, Pritam Das, Avijit Dhara +5
Spin-valley coupling in monolayer transition metal dichalcogenides gives rise to valley polarization and coherence effect, limited by intervalley scattering caused by exciton-phono…
Additional excitonic features and momentum-dark states in ReS2
Avijit Dhara, Devarshi Chakrabarty, Pritam Das +4
Unidirectional in-plane structural anisotropy in Rhenium-based transition metal dichalcogenides (TMDs) introduces a new class of 2-D materials, exhibiting anisotropic optical prope…
