摘要

The present research deals with the effect of red laser irradiation on the structural properties of MawsoniteCu_6Fe_2SnS_8 [CFTS] thin films. The was prepared using semi-computerized spray pyrolysis technique (SCSPT), it is the first time that this technique is used in the preparation and irradiation using a laser. The obtained films were irradiated by continuous red laser (700 nm) with power (>1000mW) for different laser irradiation time using the different number of times a laser scan (0, 6, 9, 12, 15, and 18 times) with a total irradiation time (0,30,45,60,75,90 min) respectively at room temperature. The XRD diffraction gave polycrystalline nature with a tetragonal crystal system. The result was that the structural properties of Mawsonite Cu_6Fe_2SnS_8 thin films affected by laser irradiation, where the XRD measurement the result was the grain size and stress values that decrease with increasing irradiation time, whereas the values of intensity, FWHM, and d-spacing for the largest peak increase with a slight increase with the increase in the irradiation time and a slight increase in growth of some peaks with increasing irradiation time. While not affected EDX and FTIR measurements by laser irradiation, the result was the same for all samples. As for AFM measurement showed that the surface roughness, root mean square, and average diameter values decrease with increasing irradiation time. Note from SEM measurement that the surface topography affected with different time of irradiation red laser. This result due to laser irradiation worked like annealing temperature to enhance the crystallization of the deposited films. As the results showed that the laser irradiation method has a clear change in the structural properties with less time and energy than the traditional annealing methods which is the aim of this study.
