Exciton diffusion in a hBN-encapsulated monolayer MoSe2
T. Hotta, S. Higuchi, A. Ueda +7
Excitons, quasi particles composed of an electron and a hole, play an important role in optical responses in low-dimensional nanostructures. In this work, we have investigated exci…

Nonlinear Photoluminescence in Atomically Thin Layered WSe2 Arising from Diffusion-Assisted Exciton-Exciton Annihilation
Shinichiro Mouri, Yuhei Miyauchi, Minglin Toh +3
We studied multi-exciton dynamics in monolayer WSe2 using nonlinear photoluminescence (PL) spectroscopy and Monte Carlo simulations. We observed strong nonlinear saturation behavio…
