                         was observed in a p-type Pb1-xSnxTe film for temperatures varying 
                         from 300 K down to 85 K. We found that this effect is a 
                         consequence of defect states located in the bandgap which act as 
                         trapping levels, changing the relation between generation and 
                         recombination rates. Theoretical calculations predict 
                         contributions to the NPC from both conduction and valence bands, 
                         which are in accordance with the experimental observations.",
