Investigation of Group-IV-A Metal Vapor Generation and Flux Behavior
Abstract
The results of this work constitute a portion of a study investigating the potential of several Group IV-A metal oxides, such as SnO* for producing an electronic transition (visible) chemical laser via the oxidation of metal atoms by N2O. The vapor composition of Sn, Ge and Si was investigated by high temperature mass spectrometry up to temperatures where the respective vapor pressures reached one torr or higher. In the case Sn and Si, 95% and 90%, respectively of the vapor exists in the atomic form; the rest exists in the form of dimers, trimers, and tetramers. The germanium vapor consists of 98% atomic species and traces of Ge2. The reaction between titanium and boron was utilized to demonstrate the generation high density tin vapor. Emission spectra of the Sn/N2O system (where Sn was generated by RF heating and/or via the Ti/B reaction) suggest that the intensity of the green system SnO is reduced with increasing density of tin vapor.
