Abstract :
The results of investigation of terahertz generation in Al0.2Ga0.8As nanowires by the optical excitation of femtosecond pulses are presented. It is shown that the radiation is generated by excitation of photocarriers in nanowires. The time-resolved dynamics of photocarriers were studied by optical-pump terahertz generation-probe time-domain spectroscopy.
