Abstract

The effect of surface chemical treatment on current-voltage (IV) characteristics of high-resistance MBE-grown PbSnTe:In films in space charge limited current (SCLC) regimes has been studied. At T=4.2 K depending on surface chemical treatment the current in films in SCLC regimes under no illumination could rise up to 104 times and even more. The surface chemical treatment also affected both the value and behavior of the photocurrent. The qualitative model for the observed phenomena has been discussed.
