Abstract
A significant enhancement of THz radiation from an InAs clean (100) surface is observed with irradiation of femtosecond laser pulses at 50 K. Due to the surface cleaning and cooling temperature, the THz-radiation intensity from the InAs clean (100) surface at 50 K becomes to 10 times larger than that from an uncleaned surface at room temperature.Keywords
