The Effect Of Substrate Temperature On The Optical and Structural Properties Of Tin Sulfide Thin Films


Tin Sulfide thin films were prepared on glass substrate by spray pyrolysis technique .X-ray diffraction confirmed the polycrystalline SnS phase with preferential orientation along (111) plane .The effect of substrate temperature on structural and optical properties was studied. The optical direct allowed band gap was varied in the range (1.6- 1.54)eV as substrate temperature increases which may be attributed to the increase in the grain size and then decrease in the strain .
