EUClass = not listedIndium(III) oxide (In2O3) is a
chemical compound , anamphoteric oxide ofindium . It formsbixbyite -typecubic crystal s.Indium oxide is used in some types of batteries,
thin film infrared reflectors transparent for visible light (hot mirror s), someoptical coating s, and someantistatic coating s.In combination with
tin dioxide , indium oxide formsindium tin oxide (also called tin doped indium oxide or ITO), a material used for transparent conductive coatings.In semiconductors, indium oxide can be used as an
n-type semiconductor used as a resistive element inintegrated circuit s. [http://www.ceramic-materials.com/cermat/oxide/in2o3.html]Thin films of indium oxide can be prepared by sputtering of indium target in
argon /oxygen atmosphere. They can be used asdiffusion barrier s ("barrier metal s") insemiconductor s, eg. to inhibitdiffusion betweenaluminium andsilicon . [http://authors.library.caltech.edu/2310/]Monocrystal linenanowire s were synthetized from indium oxide by laser ablation, allowing precise diameter control down to 10 nm.Field effect transistor s were fabricated from those. [http://www.annalsnyas.org/cgi/content/abstract/1006/1/104] Indium oxide nanowires can serve as sensitive and specificredox protein sensor s. [http://www.foresight.org/Conferences/MNT11/Abstracts/Rouhanizadeh/index.html]Sol-gel method is another way to prepare the nanowires.Indium oxide can serve as a
semiconductor material , formingheterojunction s with p-InP, n-GaAs, n-Si, and other materials. A layer of indium oxide on a silicon substrate can be deposited from anindium trichloride solution, a method useful for manufacture ofsolar cell s. [http://www.freepatentsonline.com/4436765.html]In
histology , indium oxide is used as a part of some stain formulations.Thin films of
chromium -doped indium oxide (In2-xCrxO3) was recently reported to be amagnetic semiconductor displaying high-temperatureferromagnetism , single-phase crystal structure, andsemiconductor behavior with high concentration ofcharge carrier s. It has possible applications inspintronics as a material for spin injectors. [http://www.hpcwire.com/hpc/670180.html] [http://www.hwscience.com/HWJS/archives/CIO/CIO.html]References
