中文摘要：

扫描探针电子能谱学是正在发展中的一种结合了扫描隧道显微技术的电子能谱学技术,可以原位地获得固体表面的形貌和能谱信息。本文针对新研制的扫描探针电子能谱仪专门设计制作了一台采用横向隧道结结构、小巧紧凑、稳定对称的扫描隧道显微镜,可以工作在隧道区测量样品表面形貌,也可以在近场发射区测量表面背散射电子能谱。在高定向热解石墨和石墨基底上蒸镀的银膜样品的得到的原子分辨、纳米结构图像和原位电子能量损失谱表明这两种功能已完全实现。

英文摘要：

A novel scanning probe electron energy spectrometer（ SPEES）,a combination of scanning tunneling microscope（ STM） and electron energy analyzer,was sucessfully developed,which is capable of measuring surface microstructures at an atomic scale in STM mode and alternatively evaluating in-situ the surface electronic structures in ultra high vacuum（ UHV） in SPEES-mode for spectrocopic mapping. In the lab-built,compact,rigid and stable STM,the sample and tip are fixed on a pair of vertical piezo-tubes,respectively; and the horizontally orienteated sample-tip distance can be precisely adjusted by the inertia motor and the piezo tube,respectively. The surface atomic image of highly oriented pyrolytic graphite（ HOPG） was observed in STM mode in ambient environment; and the Ag thin films deposited on HOPG was imaged in STM mode,and then the electron back-scattering spectrum was in-situ investigated in SPEES mode in UHV.
