摘要：
The switching effect, field and temperature dependences of the permittivity and conductivity of TlGaTe2 crystals subjected to various gamma-irradiation doses are studied. Under rather low electric fields, the phenomenon of threshold switching with an S-shaped current-voltage characteristic containing a portion with negative differential resistance is observed in the crystals. In the region of critical voltages, current and voltage oscillations and imposed modulation are observed. Possible mechanisms of switching, ionic conductivity, disorder, and electrical instability in TlGaTe2 crystals are discussed.
