Effect of Graphene on Improved Photosensitivity of MoS2-Graphene Composite Based SchottkyDiode

•MoS2 and MoS2-Graphene (MGC) composite have been synthesized by hydrothermal process.•Electrical properties of Al/MoS2/ITO and Al/MGC/ITO Schottky diode were studied by conventional current-voltage measurement.•The photosensitivity of composite based diode increased by almost 33 times compared to pure MoS2 based diode.•The charge transport mechanism of Schottky barrier diode was discussed by employing space charge limited current (SCLC) theory.
