| Abstract(in English) | Wide-gap semiconductors have received significant attention for their advantages over existing semiconductors. Here, We report studies on laser-induced terahertz (THz) emission from GaN. We found that the THz emission is enhanced by defects related to yellow luminescence, and this phenomenon is explained through the modification of band structures in the surface depletion layer owing to trapped electrons at defect sites. Our results demonstrate that the surface potential in a GaN surface could be detected by laser-induced THz emission. |
