Dominant Role of Sulphur divacancy in Charge Trapping Dynamics in MoS
Srest Somay, Sitangshu Bhattacharya, Krishna Balasubramanian
Intrinsic defects govern carrier trapping and recombination in two-dimensional semiconductors, yet the microscopic origin of defect-dependent capture dynamics remains unclear. Here…
Exciton-driven giant non-linear overtone signals from buckled hexagonal monolayer GaAs
Himani Mishra, Sitangshu Bhattacharya
We report here a giant 780 pm/V second harmonic and 1.410 m/V third harmonic signal from single a…
Giant exciton-phonon coupling and zero-point renormalization in hexagonal monolayer boron nitride
Himani Mishra, Sitangshu Bhattacharya
We report here a giant zero-point energy renormalization of 273 meV in the direct band-gap at and a 571 meV of blue-shifting in the position of the doubly-degenerate b…
Exciton-Phonon Coupling and Band-Gap Renormalization in Monolayer WSe
Himani Mishra, Anindya Bose, Amit Dhar +1
Using a fully ab-initio methodology, we demonstrate how the lattice vibrations couple with neutral excitons in monolayer WSe2 and contribute to the non-radiative excitonic lifetime…
