Abstract
On page 936, W. Hu, L. Liao, and co-workers develop a new type of graphene/InAs nanowire (NW) vertically stacked heterojunction infrared photodetector. This device exhibits a high photoresponsivity and a high photocurrent on/off ratio. The Fermi level of graphene can be widely tuned by the gate voltage due to its 2D nature. As a result, the back-gated bias can modulate the Schottky barrier at the interface between the graphene and InAs NWs, thus further controlling photocarrier transport across the vertically stacked heterostructures.
