  • Abstract
    We report on the observation of terahertz (THz) radiation emitted from monoclinic bismuth vanadate (BiVO4) and gold (Au) thin film interfaces, irradiated with femtosecond laser pulses. The emitted terahertz pulses show a second-order dependence on the pump power. THz radiation was measured for different thicknesses of BiVO4 and the possible reasons for this thickness dependence are also discussed.
