Abstract

Abstract : The control of exciton and trion dynamics in bilayer MoS2 is demonstrated, via the comodulations by both temperature and electric field. The calculations here show that the band structure of bilayer MoS2 changes from indirect at room temperature toward direct nature as temperature decreases, which enables the electrical tunability of the K–K direct PL transition in bilayer MoS2 at low temperature.
