Dft Study Of The Effects Of Co And Ni Impurities On

The Co- and Ni-bearing pyrite 100 surfaces were studied using density functional theory DFT. The calculated results show that the covalency of the bonds on surface is weakened due to the presence of Co or Ni impurity especially for the Ni-bearing pyrite surface. Hybridiation occurs between Co 3d and S 3p and between Ni 3d and S 3p. The electrical conductivity of surface is enhanced due

Increasing The Band Gap Of Iron Pyrite By Alloying With

2013-1-9gap of iron pyrite FeS 2 can be increased from 1.0 to 1.21.3 eV by replacing 10 of the sulfur atoms with oxygen atoms i.e. 10 O S impurities. O S formation is exothermic and the oxygen atoms tend to avoid OO dimeriation which favors the structural stability of homogeneous FeS 2x O x alloys and frustrates phase
