Wafer-scale 2H-MoTe2/perovskite quantum dot phototransistors with light-modulated ambipolar transport
Here, we report wafer-scale 2H-MoTe2/perovskite quantum dot phototransistors that exhibit light-modulated ambipolar charge transport. CsPbBr3 quantum dots are monolithically integrated with 2H-MoTe2 films grown by cold-wall chemical vapor deposition, enabling uniform device fabrication over entire 2-in. wafer. Under 40...
