Terahertz Pulse Emission from Semiconductor Heterostructures Caused by Ballistic Photocurrents
Terahertz radiation pulses emitted after exciting semiconductor heterostructures by femtosecond optical pulses were used to determine the electron energy band offsets between different constituent materials. It has been shown that when the photon energy is sufficient enough to excite electrons in th...
