在透射电子显微镜和样品制备的最新进展，现在允许复兴一个旧的想法，最初是由马顿，使用单晶作为振幅分割分束器。作为实现三晶体电子干涉仪的方向的第一步，我们提出了从双晶体干涉仪，其中两个晶体之间的差距是在实验控制和完美的注册获得通过使用聚焦离子束铣削从单个Si晶体制造的干涉仪的结果。
Recent advances in transmission electron microscopy and specimen preparation now permit the revival of an old idea, originally pioneered by Marton, of using single crystals as amplitude division beam splitters. As a first step in the direction of realizing a three crystal electron interferometer, we present results obtained from a double crystal interferometer, in which the gap between the two crystals is under experimental control and perfect registry is obtained by using focused ion beam milling to fabricate the interferometer from a single Si crystal.
