【 摘 要 】
We report on experimental observation and studies of terahertz emission from n-doped GaN films under continuous wave interband photoexcitation at low temperatures. Properties of the terahertz emission testify that the emission is caused by intracenter optical transitions in shallow donors of GaN. The THz intracenter optical transitions are initiated by the interband photoexcitation.
