Formation of metastable phases of ferrous sulfide via pulsed Nd:YAG laser deposition: Experimental and theoretical study

Nd:YAG laser ablative deposition of ferrous sulfide results in remarkable phase transformations and formation of nanocrystalline metastable rhombohedral smythite Fe9S11 and orthorhombic marcasite FeS2m phases along with stable cubic pyrite FeS2 and amorphous phase. Phase composition differs in dependence with used substrate. The electronic band structure, the angular momentum character of various structures and the electronic charge density distribution were calculated via the DFT calculations.482
