Abstract: Experimental results on the photoconductivity dynamics in PbSnTe:In films with a high SnTe content and corresponding fundamental absorption edge near 30 $\mu$m at liquid helium temperatures are reported. The possible causes for the giant (over two orders of magnitude) negative photoconductivity of the samples are discussed.
