Impurities In Iron Pyrite

Increasing the Band Gap of Iron Pyrite by Alloying with

15-8-2012Systematic density functional theory studies and model analyses have been used to show that the band gap of iron pyrite (FeS2) can be increased from ∼1 0 to 1 2–1 3 eV by replacing ∼10% of the sulfur atoms with oxygen atoms (i e ∼10% OS impurities) OS formation is exothermic and the oxygen atoms tend to avoid O–O Get price
