The photoresponse in multilayer graphene on a lithium niobate crystal (LiNbO3) was studied under the conditions of an electric potential applied to graphene and transmission of a surface acoustic wave (SAW). It is shown that the acoustoelectric current in graphene when irradiated with light either increases or decreases depending on the polarity of the potential applied to graphene. SAW causes the appearance of a periodic charge lattice in graphene, which enhances the interaction with incident light, which leads to an increase in the photoresponse.
