Ionization of DX-centers in AlGaAs : Te has been investigated in strong terahertz electric fields of FIR-laser radiation with photon energies much smaller than the impurity binding energy. Detachment of electrons from DX-centers is caused by phonon-assisted tunneling being independent of the field frequency as long as the tunneling time is smaller than the field period. In the opposite case an ...
