DETAILS

Apollo Scientific Ltd - PC4388

Cylinder - 1/4" NPT connection

Sigma Aldrich - 463000

Application
Employed in studies on room-temperature oxidation of noble metals1 and the fabrication of SiGe crystallites on glass substrates.2
Germanium(IV) fluoride in combination with disilane gas has recently been used to fabricate SiGe crystallites directly on glass substrates. Intense visible light emission from Ge and Si nanocrystals is of particular interest because of potential uses in optoelectronic devices.
