Characterization of FeS2-pyrite thin films synthesized by sulphuration of amorphous iron oxide films pre-deposited by spray pyrolysis

Morphology controllable syntheses of micro- and nano-iron pyrite mono- and poly-crystals: a review

“…Many types of precursor materials have been employed in the reported studies, including iron lms, [91][92][93][94][95][96][97][98][99] iron oxide lms, 100-105 iron sulphide lms 106,107 and other typical chemicals. 1,[108][109][110][111][112][113][114][115][116][117] The terminal morphology of iron pyrite is determined by the precursor materials. When the precursor materials are lms, nanotubes or nanowires, so are the terminal pyrite samples.…”

The contribution of grain boundary barriers to the electrical conductivity of titanium oxide thin films

“…For our TiO x thin films, the H coefficient is enhanced from 0.88 to 3.1 with the t ON injection time, which are typical values previously reported for other semiconducting compounds. [12][13][14] In undoped and substoichiometric TiO 2 thin films, it is commonly admitted that the conductivity change is closely linked to the mobile charge carriers. 15 Their concentration originates from point defects, i.e., mainly oxygen vacancies rather than interstitial titanium atoms.…”

Deposition of iron sulfide thin films by AACVD from single source precursors

“…Schleigh and Chang [15] deposited FeS 2 thin films using iron pentacarbonyl [Fe(CO) 5 ], hydrogen sulfide, and tert-butyl sulfide as precursors by LPCVD. Other techniques include sulfurization of iron oxides to FeS 2 [19,20], ion beam and reactive sputtering (FeS 2 ) [21], plasma assisted sulfurization of iron (FeS 2 ) [22], flash evaporation (FeS 2 ) [23], vacuum thermal evaporation (FeS 2 ) [24], vapor transport (FeS 2 ) [25], and chemical spray pyrolysis (FeS 2 ) [26]. Different phases of iron sulfide nanoparticles were produced by high-energy mechanical milling combined with mechanochemical processing for FeS and FeS 2 [27], dendrimer-stabilized FeS [28], solvothermal synthesis of Fe 3 S 4 [29], sulfur-reducing bacteria for Fe 1 À x S and Fe 3 S 4 [30,31], laser pyrolysis of iron complexes for FeS [32], polymer-stabilized wet chemical synthesis of FeS [33], reverse micelles for FeS 2 [34], and the decomposition of single-source precursors for FeS 2 [35].…”
