Few-Layer MoS/a-Si:H Heterojunction pin-Photodiodes for extended Infrared Detection

Andreas Bablich, Daniel S. Schneider, Paul Kienitz +11

Few-layer molybdenum disulfide (FL-MoS) films have been integrated into amorphous silicon (a-Si:H) pin photodetectors. To achieve this, vertical a-Si:H photodiodes were grown b…
