PbSe thin films were grown using PLD method on the p-Si(100) substrate. To determine what crystalline structure of PbSe thin films have according to the growth temperature, the films were prepared under a substrate temperature changing between a room temperature and $400^{circ}C$. As a result of analyzing XRD patterns of PbSe thin films prepared at various substrate temperatures and FWHM of PbSe(200) rocking curve, it was found that PbSe thin film obtained at the growth temperature of $200^{circ}C$ was best crystallized. In addition, the surface morphology of PbSe thin film observed using AFM found itself having the most regularly arranged particles in case of growing the film at $200^{circ}C$. The measurement of Hall effect indicated that PbSe thin films were n-type semiconductors and that current-voltage characteristic curve exhibit the typical p-n junction phenomenon. In addition, electric conductivity of PbSe thin films was found somewhat higher than that of general semiconductors.
