We report on the first demonstration of photodetector as well as the observation of photovoltaic effect based on vertical transport in multilayer \alpha -In 2 Se 3 . A metal/ \alpha -In2Se 3 /ITO vertical junction was used to achieve an ultra-high responsivity of 1000 A/W even at a low bias of 0.5 V...
