Abstract:
This paper reviews unusual photoelectric effects observed in doped narrow-gap PbTe-based semiconductors exposed to intense terahertz laser pulses. It is shown that in some cases these effects are due to those (nontrivial) local electronic states that, unlike ordinary, spectrally defined impurity states, are linked to the quasi-Fermi level, whose position can be varied by changing the degree of photoexcitation.
