论文摘要
我们已经开发了一种将静态扫描电子显微镜成像扩展的技术，以包括快速热和外部驱动运动的高光谱映射到Megahertz频率。它基于对运动对象上的聚焦电子束产生的二级电子通量的光谱分析。我们证明了纳米线布朗运动的检测和具有深层亚纳米位移敏感性的跳蚤刚毛刺激振荡的高光谱映射。
We have developed a technique that extends static scanning electron microscopic imaging to include hyperspectral mapping of fast thermal and externally-driven movements at up to Megahertz frequencies. It is based on spectral analysis of the secondary electron flux generated by a focused electron beam incident on the moving object. We demonstrate detection of nanowire Brownian motion and hyperspectral mapping of stimulated oscillations of flea setae with deep sub-nanometer displacement sensitivity.
