Abstract
Temperature‐dependent structure in the photoenhancement of nonlinear surface‐acoustic‐wave convolution on ZnO is reported. Measurements of the temperature dependence of surface‐wave convolution without light, thermally stimulated conductivity, and photoconductivity suggest that the photoenhancement effect in ZnO is sensitive to trapping and surface preparation. A possible model for the dependence of photoenhancement on photon wavelength is proposed.Keywords
