Two-dimensional Photoelectron Spectroscopy from Micro Region

本研究的目的是研制一种新型的体视显微镜（显示型椭球网格分析仪），使我们能够从很小的区域进行二维光电子能谱，观察样品的放大图像以及它们的电子和原子结构。在SPring-8进行了性能评价。能量分辨率为0.2%，图像分辨率为25 μ m，接收角为±50 °。成功地获得了小图形的光电子衍射图。一种新显微镜的研制成功了。

The purpose of this study is to developa new stereo-microscope (Display-type Ellipsoidal Mesh Analyzer) which enables us to observe magnified image of the sample as well as their electronicand atomic structure by performinga two-dimensional photoelectron spectroscopy from only small area. Performance evaluation was made at SPring-8. A good energy resolutionof 0.2%, an image resolution of 25 micron, wide acceptance angle of ±50 degree were confirmed. Photoelectron diffraction pattern from small graphemewas successfullyobtained. The development ofa new microscope was succeeded.
