The pyrite films with the thickness of 70–600 nm were prepared by annealing the iron films with the thickness of 25–150 nm at 673 K. The structural, optical and electrical characteristics were investigated and the effect of film thickness on film properties was discussed. The pyrite films with different thickness have the optical absorption edges changed in the 0.93–1.0-eV range. With the increase...
Pyrite films have been prepared by sulfuration annealing iron films with different sulfur atmosphere pressure at 400 and 500 o C. The optical absorption and electrical characteristics have been determined as a function of the sulfur pressure in the range of 40-100 kPa. For the films sulfurated at 400 o C, with increasing in sulfur pressure, the optical absorption edge increases up...
