From: Photodiode-Like Behavior and Excellent Photoresponse of Vertical Si/Monolayer MoS2 Heterostructures
(a) The schematic illustration of experimental setup of Si/MoS2 heterostructures. Conductive AFM with Co/Cr tip was grounded and applied to measure the electrical behavior of Si/MoS2 heterostructures upon light illumination with different light wavelengths and power densities. (b) The I–V curves dependent on the tip-sample contact force. The inset presents the I–V curve with larger contact force of 20 nN. The reverse bias increased rapidly, which may be resulted from the significant plastic deformation or even mechanical breakdown of monolayer MoS2.
