Ganichev, Sergey and Diener, J. and Yassievich, Irina and Prettl, Wilhelm and Meyer, B. and Benz, K. (1995) Tunnelling ionization of autolocalized DX- centers in terahertz fields. Physical Review Letters 75 (8), pp. 1590-1593.
Tunneling ionization of DX- centers in AlxGa1-xSb has been observed in terahertz radiation fields. Tunneling times have been measured for autolocalized and on-site deep impurities. It is shown that in one case the tunneling time is smaller and in the other larger than the reciprocal temperature multiplied by a universal constant due to the different tunneling trajectories. This allows one to distinguish in a direct way between the two types of configuration potentials of impurities.
