Electrical Relaxation and Transport Properties of ZnGeP<sub>2</sub> and 4H-SiC Crystals Measured with Terahertz Spectroscopy

Terahertz photoconductivity and charge carrier recombination dynamics at two-photon (ZnGeP<sub>2</sub>) and three-photon (4H-SiC) excitation were studied. Thermally annealed, high-energy electron-irradiated and Sc-doped ZnGeP<sub>2</sub> crystals were tested. The terahertz ch...
