Abstract :
An efficient terahertz (THz) emission from sol-gel grown Cu2ZnSnSe4 (CZTSe) film is evaluated using THz time domain spectroscopy. Comparing the polarity of THz emission waveforms of CZTSe and GaAs, we suggest the acceleration of photo-carriers in the surface accumulation layer of CZTSe to be the dominant mechanism of radiation emission.
