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 ...
