Optoelectronics: High‐Performance Photovoltaic Detector Based on MoTe₂/MoS₂ Van der Waals Heterostructure (Small 9/2018)

In article number 1703293, Tie Lin, Weida Hu, Jianlu Wang, and co-workers present a high performance photovoltaic photodetector based on MoTe2/MoS2 Van der Waals heterojunction. The light-induced charge transport under different biases is discussed. As self-powered photodetectors, the vertical 2D p-n junctions achieve a sensitive response and broad detection wavelength range. These properties indicate that 2D van der Waals junctions are promising for application in photo-sensing, on-chip logic circuits and so on.
