A mixed film consisting of 2D MoS₂ and graphene oxide (GO) nanosheets is used to fabricate memory devices. The conductive MoS₂ component in the MoS₂-GO film increases the film conductivity, thus facilitating oxygen migration in GO. The MoS₂-GO film-based device exhibits rewritable, nonvolatile, electrical bistable switching with low switching voltage (≤ 1.5 V) and high ON/OFF current ratio (≈ 10²).
