扫描隧道显微镜和光谱实验表明，通过选择具有适当功函数的基底系统，可以控制吸附在表面上的单个分子的电荷状态。使用差异图像研究附加电荷的分布。这些图像显示出明显的分子内对比度。
From scanning tunneling microscopy and spectroscopy experiments it is shown that control over the charge-state of individual molecules adsorbed on surfaces can be obtained by choosing a substrate system with an appropriate workfunction. The distribution of the additional charge is studied using difference images. These images show marked intramolecular contrast.
