Biexcitons in Monolayer Transition Metal Dichalcogenides Tuned by Magnetic Fields

ORAL

Abstract

Time-Integrated Four Wave Mixing measurements were performed on CVD grown MoSe2 monolayers. The dephasing lifetime was investigated in magnetic fields up to 25T. Additionally, the effects of valley selection on the lifetime was explored through varying polarization schemes. The results were then modeled using time-dependent density function theory revealed the dephasing lifetime is dominated by the inter-valley biexcitons.
