Autoignition =Indium(III) selenide is a compound of
indium andselenium . It has potential for use in photovoltaic devices and it has been the subject of extensive research. The two most common forms α- and β- have defect wurtzite structures, however there are five known forms (α, β, γ, δ, κ) ["Crystal structure of κ-In2Se3." Jasinski, J.; Swider, W.; Washburn, J.; Liliental-Weber, Z.; Chaiken, A.; Nauka, K.; Gibson, G. A.; Yang, C. C.Applied Physics Letters, Volume 81, Issue 23, id. 4356 (2002) 10.1063/1.1526925] The α- β phase transition is accompanied by a change from metallic conduction. [ "Some Electrical and Optical Properties of In2Se3" D. Bidjin, S. Popovi , B. Elustka Physica Status Solidi (a) Volume 6, Issue 1 , Pages 295 – 299 DOI 10.1002/pssa.2210060133 ] The band-gap of γ-In2Se3 is approximately 1.9 eV. The crystalline form of a sample can depend on the method of production, for example thin films of pure γ-In2Se3 have been produced fromtrimethylindium , InMe3, andhydrogen selenide , H2Se, usingMOCVD techniques ["Growth of single-phase In2Se3 by using metal organic chemical vapor deposition with dual-source precursors" Chang, K. J.; Lahn, S. M.; Chang, J. Y. Applied Physics Letters, Volume 89, Issue 18, id. 182118 (3 pages) (2006). DOI: 10.1063/1.2382742]ee also
