Abstract

THz time-domain spectroscopy is applied to probe photo-induced charge transport in single-crystal Al2O3. The conductivity of the material and its temporal evolution yield carrier mobilities, excitation densities, and dynamics. The temperature dependence indicates that LO phonons are the dominant scattering mechanism.
