标题: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.

摘要:Synthesis of silanes with more than three silicon atoms are disclosed (i.e., SinH(2n+2) with n=4-100). More particularly, the disclosed synthesis methods tune and optimize the isomer ratio by selection of process parameters such as temperature, residence time, and the relative amount of starting compounds, as well as selection of proper catalyst. The disclosed synthesis methods allow facile preparation of silanes containing more than three silicon atoms and particularly, the silanes containing preferably one major isomer. The pure isomers and isomer enriched mixtures are prepared by catalytic transformation of silane (SiH4), disilane (Si2H6), trisilane (Si3H8), and mixtures thereof.

摘要:Methods of selectively synthesizing n-tetrasilane are disclosed. N-tetrasilane is prepared by catalysis of silane (SiH4), disilane (Si2H6), trisilane (Si3H8), or mixtures thereof. More particularly, the disclosed synthesis methods tune and optimize the n-tetrasilane:i-tetrasilane isomer ratio. The isomer ratio may be optimized by selection of process parameters, such as temperature and the relative amount of starting compounds, as well as selection of proper catalyst. The disclosed synthesis methods allow facile preparation of n-tetrasilane.
