Abstract

The MoS 2 /ZnO and MoS 2 /Si heterojunction structures were fabricated by thermal evaporation and sol-gel methods. The crystal structures properties of MoS 2 /ZnO and MoS 2 /Si were characterized by X-ray diffraction (XRD) pattern, Raman spectroscopy, and transmission electron microscope (TEM). The XRD and Raman spectroscopy results indicate that the n-MoS 2 film was successfully grown on p-doped ZnO or Si. The TEM images of MoS 2 /ZnO and MoS 2 /Si heterojunction structures shows the MoS 2 stacking layer-by-layer covalented by van der Waals (vdW) force. The current–voltage (I–V) measurement shows the rectifying behavior of the heterojunction structures. The photoconductivity and photoresponsivity properties explore its carrier kinetic decay process. The results shows the potential applicability of MoS 2 /ZnO and MoS 2 /Si heterojunction structures as optoelectronic devices.
