Abstract

The gas phase ion-mol. reactions of GeH4 with CO, CO2, and C2H4 have been studied by high-pressure mass spectrometry and Fourier transform mass spectrometry. The effects of the total pressure and of the relative concns. of the reagent gases on the ion pattern are reported. In the presence of CO and CO2, GeHnCO+ or GeHnCO2+, GeHnO+, and GeHnC+ ions are obsd., all of which show very low abundances. In contrast, condensation processes of GeH4 with C2H4 give GeCnHm+ (n = 1-4) species, in very high yield for n = 1, 2 but lower for n = 3, 4. For all three systems, reaction mechanisms are suggested and are discussed in relation to the prepn. of amorphous materials contg. germanium carbides for photovoltaic applications.
