Abstract In building up molecular circuits and molecule-based devices, it is central to determine how molecules interact with the surface. Here, we explore the behaviour of a bifunctional molecule, i.e. phenol, on Si(111)7 × 7 by high resolution photoemission, comparatively in the C1s, Si2p, VB and O1s energy ranges. We found out that the adsorption is more complex than originally hypothesized with a mixture of dissociative and molecular adsorbates at low exposures, and a preeminence of dissociative adsorbates at higher exposure. The co-existence of these states is different from the Si(100) surface, where the molecular states are readily converted into dissociative ones.

高分辨率光电发射揭示Si(111)7×7上苯酚的多种选择

摘要 在构建分子电路和基于分子的设备时，确定分子如何与表面相互作用至关重要。在这里，我们比较在 C1s、Si2p、VB 和 O1s 能量范围内，通过高分辨率光电发射探索双功能分子，即苯酚，在 Si(111)7 × 7 上的行为。我们发现吸附比最初假设的更复杂，在低暴露条件下解离和分子吸附物的混合物，以及在较高暴露下解离吸附物的卓越表现。这些状态的共存与 Si(100) 表面不同，Si(100) 表面的分子状态很容易转化为离解状态。
