Photoresponse of atomically thin MoS2 layers and their planar heterojunctions
Sangeeth Kallatt, Govindarao Umesh, Navakanta Bhat +1
MoS2 monolayers exhibit excellent light absorption and large thermoelectric power, which are, however, accompanied with very strong exciton binding energy - resulting in complex ph…

Valley Coherent Hot Carriers and Thermal Relaxation in Monolayer Transition Metal Dichalcogenides
Sangeeth Kallatt, Govindarao Umesh, Kausik Majumdar
We show room temperature valley coherence with in MoS2, MoSe2, WS2 and WSe2 monolayers using linear polarization resolved hot photoluminescence (PL), at energies close to the excit…
