The work presents and analyzes the results of detecting the photoacoustoelectric effect of surface acoustic waves amplification by illumination of a hybrid graphene-LiNbO3 structure. This SAW photoamplification effect is associated with the appearance of an additional photoacoustoelectric current and a decrease of collisional scattering of photoinduced electrons under the action of the SAW electric field. Possible mechanisms of SAW amplification based on the analysis of modern data are discussed. This SAW photoamplification effect can be used to create optoacoustoelectronic devices on a graphene-piezoelectric structures for collecting, amplifying, and detecting superweak sources of THz-radiation photons.
