## Description

- description: Van der Waals (vdW) heterostructures, which can be assembled with various
    two-dimensional materials, provide a versatile platform for exploring emergent
    phenomena. Here we report an observation of the photovoltaic effect in a WS2/MoS2
    vdW heterostructure. Light excitation of WS2/MoS2 at a wavelength of 633 nm yields
    photocurrent without applying bias voltages, and excitation power dependence of
    photocurrent shows characteristic crossover from liner to square root dependence.
    Photocurrent mapping has clearly shown that the observed photovoltaic effect arises
    from WS2/MoS2 region, not from Schottky junctions at electrode contacts. Kelvin
    probe microscope observations show no slope in electrostatic potential, excluding
    the possibility that the photocurrent originates from an unintentionally formed
    built-in potential.
