Title: Near-infrared photoactive Cu{sub 2}ZnSnS{sub 4} thin films by co-sputtering

The thin films of Cu{sub 2}ZnSnS{sub 4} (CZTS) were grown by co-sputtering further the structural, optical and electrical properties were analyzed and confirmed the CZTS phase formation. The photo response of CZTS in near IR photodectection has been demonstrated. The detector response was measured employing both the IR lamp and IR laser illuminations. The calculated growth and decay constants were 130 m sec and 700 m sec followed by the slower components upon lamp illumination. The external quantum efficiency of 15%, responsivity of 13 AW{sup −1} makes CZTS a suitable candidate for the IR photodectection.
