Making the well-defined contacts between molecules and substrates in nm scale and their electronic properties

我们制备了纳米尺度的分子-基底接触系统，并研究了其结构和电子性质。阐明了烯烃在Si（100）c（4x 2）上的环加成反应机理。我们用红外吸收光谱表征了附着在Si（111）表面的烷基单层膜，并用汞电极研究了其电子输运性质。作为金属电极在水中的模型体系，我们研究了水在Rh（111）上的吸附。此外，我们还研究了DBP-S和F4-TCNQ分子在Cu（100）表面的吸附态和电子性质。用红外吸收光谱研究了环己烷与Rh（111）的弱相互作用，阐明了CH伸缩振动软化的机理。

We have fabricated the well-defined molecule-substrate contact systems in nm scale and investigated the structural and electronic properties. We elucidated the mechanism of cycloaddition of alkene on Si(100)c(4x2). We have characterized the alkyl monolayer attached to the Si(111) surface using infrared absorption spectroscopy and investigated the electron transport properties using a mercury electrode. As a model system for a metal electrode in water, we investigated water adsorption on Rh(111). In addition, we investigated the adsorbed states and electronic properties of DBP-S and F4-TCNQ molecules on Cu(100). The weak interaction between cyclohexane and Rh(111) was studied using infrared absorption spectroscopy and elucidated the softening mechanism of CH stretching vibration.
