Trion Formation Dynamics in Monolayer Transition Metal Dichalcogenides
Akshay Singh, Galan Moody, Kha Tran +13
We report charged exciton (trion) formation dynamics in doped monolayer transition metal dichalcogenides (TMDs), specifically molybdenum diselenide (MoSe2), using resonant two-colo…
Electrical Control of Second-Harmonic Generation in a WSe2 Monolayer Transistor
Kyle L. Seyler, John R. Schaibley, Pu Gong +7
Nonlinear optical frequency conversion, in which optical fields interact with a nonlinear medium to produce new field frequencies, is ubiquitous in modern photonic systems. However…
Population pulsation resonances of excitons in monolayer MoSe2 with sub 1 μeV linewidth
John R. Schaibley, Todd Karin, Hongyi Yu +9
Monolayer transition metal dichalcogenides, a new class of atomically thin semiconductors, possess optically coupled 2D valley excitons. The nature of exciton relaxation in these s…
Ultra-Low Threshold Monolayer Semiconductor Nanocavity Lasers
Sanfeng Wu, Sonia Buckley, John R. Schaibley +8
Engineering the electromagnetic environment of a nanoscale light emitter by a photonic cavity can significantly enhance its spontaneous emission rate through cavity quantum electro…
