The properties of the organic monolayers formed by grafting of alcohols on the Si(111)-H surface have been investigated by interface capacity analysis,combined with XPS and AFM technique.Some factors influencing the properties of the monolayers,their stability and passivation towards oxidation of silicon surface were examined.The results showed that under the reaction conditions used,the grafted molecules occupied about 0.80 volume fraction on the silicon surface modified by alcohol molecules of different chain length,with plat potential being about -1.00 V/(vs.SSE).The results demonstrated that the stability and passivation of these monolayers are deficient.
