The Effect of Deposition Time and Sulfurization Temperature on The Optical and Structural Properties of Iron Sulfide Thin Films Deposited from Acidic Chemical Baths

Abstract: Pyrite phase FeS2 thin films have been grown by a two-stage process of chemical bath deposition followed by sulfurization. Thiourea and thioacetamide were used as sulfur precursors in separate baths.  The deposition time was controlled for 1, 2, and 3 hours respectively. The as-deposited films were sulfurized at temperatures of 250 oC and 500 oC to form the pyrite phase. The effect of deposition time and sulfurization temperature on the structure, morphology and optical properties of the iron pyrite films obta… Show more

“…We used long sulfurization times for two temperatures to find the growth condition for high throughput and low-cost processing. In the past literature, time sulfurization ranged between 90 and 120 min [63,64] and was still considered short sulfurization between 3 h and 8 h [65,66].…”
