The control of exciton and trion dynamics in bilayer MoS 2 is demonstrated, via the comodulations by both temperature and electric field. The calculations here show that the band structure of bilayer MoS 2 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 MoS 2 at low temperature.
