Abstract
Lead Sulfide (PbS) in thin film form is used in many applications as ar, infrared detector . In this work amorphous lead sulfide films was prepared using different thermal evaporation techniques . Electrical and structural measurements were done upon the as grown films. In order to enhance the electrical and structural characteristics, several heat treatment processes were done at temperatures of 250., 350, 420 °C . This study showed a great improvement in the detector responsivity due to the performed heat treatments which can be simulated in other types of detector materials.
