Jan 01, 2015 The cubic FeS 2 (Pyrite) films are prepared by chemical bath deposition method (CBD) at different iron ion precursor concentrations that varying from 2.0 M to 0.5 M. X-ray diffractograms revealed that the presence of (110) plane, corresponding to marcasite structure, and (106) and (304) planes, corresponding to FeS (Triolite) phase are observed along with the pure pyrite phase (200) at higher

Jan 01, 2018 The fraction of marcasite in our MP film was estimated to be approximately 30% by comparing the intensity ratio of marcasite and pyrite Raman signals for our MP film with that for the FeS 2 film reported to contain 50% marcasite (Seefeld et al., 2013). All of these film features enabled us to investigate the detailed phase distribution and
Iron pyrite and iron marcasite thin films prepared by low
Jul 01, 1991 Thin films of iron pyrite and iron marcasite have been successfully prepared by low pressure chemical vapor deposition (LPCVD) from iron pentacarbonyl (Fe(CO) 5) and tert-butyl disulfide (TBDS) over a wide temperature range from 200 to 500°C.A series of thin film deposition reactions were studied using Fe(CO) 5 and different sulfur sources (H 2 S, tert-butyl sulfide, or tert-butyl disulfide).

to marcasite structure, and (106) and (304) planes, corresponding to FeS (Triolite) phase are observed along with the pure pyrite phase (200) at higher concentrations of iron. The films deposited at 1.0 M concentration has strong (200) and (023) planes related
Characterization of the structure and the surface
Mar 01, 2003 A thin film of marcasite, FeS 2, was synthesized under vacuum and its structure and reactivity under oxidizing conditions was investigated by means of diffraction and surface analytical techniques, respectively. X-ray diffraction of the micron-thick films showed that the film crystallized in the marcasite phase of FeS 2.Atomic force microscopy indicated that the thin film had a nanometer-scale
Pyrite (FeS2) thin films prepared by spray method using
Feb 01, 2003 By annealing deposited films in a H 2 S atmosphere at around 500°C for 30 min, a pyrite film containing no marcasite or pyrrhotite is successfully obtained. All pyrite films prepared show p-type conduction. They have a carrier concentration in the range 10 16 –10 20 cm −3 a Hall mobility in the range 200–1 cm 2 /V s.

In addition, the pyrite/marcasite film has been found to have a larger diffusion coefficient for photogenerated minority carriers than the phase-pure pyrite film from electrochemical impedance
