    Role of silylene in the deposition of hydrogenated amorphous silicon
    摘要:
    The role of silylene in the laser deposition of hydrogenated amorphous silicon has been studied with laser-induced fluorescence and deposition rate measurements. The rate constants of the reactions of silylene with silane and disilane and of the reverse reactions have been determined. The results show that silylene is rapidly consumed, exhibiting only a small effective lifetime. It proves that generally silylene will hardly be able to reach the surface to form amorphous silicon. The comparison of the kinetic data with the deposition rates shows that in IR laser CVD silylene starts the gas-phase chemistry and that disilene is the main film-forming molecule. The UV laser process starts with a different primary dissociation leading to silylsilylene, which also rearranges to the film-forming disilene.

    photodecomposition of Si/sub 2/H/sub 6/ at 147 nm results in the formation of H/sub 2/, SiH/sub 4/, Si/sub 3/H/sub 8/, Si/sub 4/H/sub 10/, Si/sub 5/H/sub 12/, and a solid film of amorphous silicon hydride (a-Si:H). Three primary processes are proposed to account for the results, namely, (a) Si/sub 2/H/sub 6/ + h..nu.. ..-->.. SiH/sub 2/ + SiH/sub 3/ + H (phi/sub a/ = 0.61); (b) Si/sub 2/H/sub 6/ + h..nu.. ..-->

    日期:2009.10.5
    Tunneling reactions of H atoms with solid Si 2 H 6 at 10 K were investigated. The in situ and real-time reactions H + Si 2 H 6 to form silane and polysilanes were monitored using FT-IR. Quantitative analysis of gaseous products was made by thermal desorption spectrometry. Monosilane and polysilanes were detected as major reaction products. The intermediate product SiH 2 was suggested to play an important

    Vacuum ultraviolet (VUV) photoionization at 10.2 eV was employed for the detection of gas-phase molecules formed after thermal decomposition of disilane at a total pressure of 30 Torr and in the temperature range of 298–740 K. The SinH2(n+1) (n=3–5) and SinH2n (n=2–5) species resulting from disilane pyrolysis in a flow reactor were directly observed using time-of-flight mass spectrometry. Unlike multiphoton
