It is shown that the process is controlled by the mass transport of SnS in gas phase. The evaporation rate of SnS is significantly enhanced by increasing tempeature and carrier gas flow rate. The apparent activation energy for the process is found to be 204.67 kJ. The evaporation rate for the present system is much smaller than that for SnS-FeS system.展开更多
