Paper Abstract

We have analyzed photoconductivity in PbSnTe(In) under the action of ~100 ns long terahertz laser pulses with the wavelength 90 - 500 μm in the temperature range 4.2-300 K. Strong photoresponse has been observed at all wavelengths used. Positive persistent photoconductivity is observed at T < 10 K, whereas negative non-persistent photoresponse prevails at higher temperatures T ~ 25 K. Specific features of photoconductivity are discussed.
