Integral imaging using a MoS2 Schottky diode

We report the performance of a MoS2 Schottky diode on three-dimensional (3D) integral imaging. The MoS2 Schottky diode has asymmetric Pt electrodes for the Schottky contact and Ti/Au electrodes for the ohmic contact. Such a Schottky diode exhibits an excellent rectification ratio of 103, a broad spectral photoresponse in the 450–700 nm range, an almost ideal linearity of 1, and a wide linear dynamic range of 106 dB. We successfully conduct object pickup experiments using integral imaging and validate the feasibility of a single-pixel imager as a 3D image sensor.
