Abstract

The control of exciton and triondynamics 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.
