Reactions of He+, Ne+, and Ar+ with CH4, C2H6, SiH4, and Si2H6

Article abstract of DOI:10.1063/1.445884

The rate coefficients and product-ion distributions for the reactions of He⁺ and Ar⁺ with silane and disilane have been measured in a drift tube, typically for collision energies of 0.01-1 eV.The total charge-exchange rate coefficients are found to be roughly independent of E/N, or collision energy, and are about equal to the Langevin values for the reactions of He⁺ with SiH4 and C2H6 and Ar⁺ with CH4 and C2H6.The He⁺ rate coefficients on CH4 and Si2H6, and the Ne⁺ rate coefficients on SiH4 and Si2H6 are 50percent to 80percent of the Langevin values, while the Ar⁺ rate coefficients on SiH4 and Si2H6 are much smaller.Product ions tend to be hydrogen poor with very infrequent breaking of the C-C or Si-Si bonds.Furthermore, hydrogen stripping is more severe for the silanes than the alkanes.These product-ion distributions bear no resemblance to the product-ion distributions of either photoionization or electron collisional ionization.
