The source of the THz radiation is believe to be either the time-dependent transport current produced by the optically generated carriers in the depletion field and/or by hot-carrier diffusion (the photo-Dember effect). These mechanisms cannot be separated by our experiments. The THz radiation power for InxGa1-xN decreases as the Ga doping concentration increases. A possible explanation for the decrease in the radiation power is the electron mobility decreases with increasing Ga doping concentration. Tsong-Ru Tsai 蔡宗儒 2006 學位論文 ; thesis 50 zh-TW
