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