AbstractThis research studied the effective of irradiation by laser on structure and electrical properties of thin film such as lead sulphid PbS, so in the beginning the film has amorphous structure and when irradiation by laser (annealed) the structure properties would change and the no. of peak appeared with different modes but the mode(200) still has large intensity compared with another modes, and the grain
size increased with increased the time of irradiation to become (7.5 to 16)nm, and for the electrical properties the film has linear ship between voltage and current, and the conductivity increased when the time of irradiation.
