Tellurium donors in GaP have been ionized by phonon-assisted tunneling in the electric field of pulsed far-infrared laser radiation. In response to the laser pulse a photoconductive signal has been detected with a fast component that follows in time the laser pulse and a slow component that rises after the irradiation has ceased and finally exponentially decays with a strongly ...
