摘要: The presence of defects leads to a significant impact on the optical and electrical properties TMDCs. photoelectric performance TMDCs can be tailored through defect engineering. In this work, we study engineering by using controlled annealing in air as an approach improve photodetector based multilayer WSe2. responsivity EQE WSe2 show obvious improvement after annealing. Furthermore, displays fast response order tens ms enhanced attributed trapping photogating effect.
