Abstract

In this work, electron energy spectroscopic mapping of surface plasmon of Ag nanostructures on highly oriented pyrolytic graphite is reported. Benefitting from the angular dispersive feature of the present scanning probe electron energy spectrometer, a multi-channel detection mode is developed. By scanning along one direction, the two-dimensional intensity distribution of Ag surface plasmon excitation due to the collision of electron emitted from the tip can be obtained in parallel. The spectroscopic spatial resolution is determined to be around 80 nm.

平行扫描法表面等离子体电子能谱成像

本文报道了高取向热解石墨上银纳米结构表面等离子体的电子能谱映射。利用现有扫描探针电子能谱仪的角色散特性，开发了一种多通道检测模式。通过沿一个方向扫描，可以平行得到银表面等离子体激元因尖端发射的电子碰撞而激发的二维强度分布。光谱空间分辨率在80 nm左右。
