Optical and structural properties of FeSe2 thin films obtained by selenization of sprayed amorphous iron oxide films

Synthesis and characterization of spray deposited nanostructured FeSe thin films

“…The band gap was found to be 2.75 eV for spray deposited FeSe film. This is higher than the value reported by other investigators [8,9].…”

Three-dimensional FeSe2 microflowers assembled by nanosheets: Synthesis, optical properties, and catalytic activity for the hydrogen evolution reaction

“…[4,5] Among these inorganic materials, FeSe 2 with a direct band gap of 1.0 eV has been regarded as a promising candidate for solar cells and for detecting visible radiation. [6][7][8][9] Moreover, FeSe 2 is considered a less toxic and more environmentally friendly semiconductor. In addition, threedimensional flower-like micro/nanostructures have been reported to exhibit unique properties and have potential applications in the fields of transistors, superconductors, photodetectors, solar cells and lithium ion batteries.…”

Growth of FeSe on general substrates by metal-organic chemical vapor deposition and the application in magnet tunnel junction devices

“…Selenization of iron thin films is an usual route to fabricate Fe-Se compounds thin films. However, it usually obtains non-oriented thin films, even mixtures of more than two Fe-Se compounds [5][6][7][8]. The unsatisfactory crystal quality limits the study on Fe-Se compounds within composition analysis and structure characterization, and accordingly restricts the research on optical, electrical properties.…”
