论文摘要
现代的纳米技术技术为在微米和亚微米水平上制造结构和设备提供了新的机会。在这里，我们使用聚焦的离子束技术来实现电子的漂移管Zernike相板，其操作基于Janus双金属圆柱体中的接触电势的存在，其方式与静电线相似的方式类似。我们使用电子Fraunhofer干扰来证明这种双金属柱结构引入了相移，可以通过改变其尺寸，尤其是其高度来调节所需值。
Modern nanotechnology techniques offer new opportunities for fabricating structures and devices at the micron and sub-micron level. Here, we use focused ion beam techniques to realize drift tube Zernike phase plates for electrons, whose operation is based on the presence of contact potentials in Janus bimetallic cylinders, in a similar manner to the electrostatic Aharonov-Bohm effect in bimetallic wires. We use electron Fraunhofer interference to demonstrate that such bimetallic pillar structures introduce phase shifts that can be tuned to desired values by varying their dimensions, in particular their heights.
