RSC-ZPS.pdf 1. 扫描隧道显微术 (STM/S)只能 获取固体表层原子的外层电子谱（费米能级附近）； 2. XPS 获取固体表面几层和体内原子混合的内层电子谱 （体信息）； 3. ZPS 提取表层原子和缺陷周围两个原子范围内的价电子和芯能级谱（表面单原子层和点分辨信息, 如图示）; 4. ZPS 不仅克服 XPS 解谱的困难而且提供关于局域键长、键能、结合能、电荷极化和钉扎等以及它们的动力学过程的定量信息； 5. ZPS（2010美国专利） 有望成为材料科学、表面科学、和界面科学领域最为快捷有效的关键技术。 Zone-selective photoelectronic measurements of the local bonding and electronic dynamics associated with the monolayer skin and point defects of graphite RSC Adv DOI: 10.1039/c2ra00512c STM/S Profiles of point defects at graphite surface evidenced the BOLS expected high protrusion and the Ef resonant peaks as arising from th epolarization of the dangling bond electrons by the localy and densely entrapped core electrons of he lesscoordinated edge carbon atoms. Findings: 1) surface bonds are shorter and stronger (Ts) than those in the bulk (B); 2) defect bonds are even shorter and stronger (TD); 3) defect dangling bond electrons are polarized (P).
