A scanning helium ion microscope (SHIM, HeIM or HIM) is an imaging technology based on a scanning helium ion beam. Similar to other focused ion beam techniques, it allows to combine milling and cutting of samples with their observation at sub-nanometer resolution. In terms of imaging, SHIM has several advantages over the traditional scanning electron microscope (SEM). Owing to the very high source brightness, and the short De Broglie wavelength of … WebThe scanning helium microscope (SHeM) is a novel form of microscopy that uses low energy (5-100 meV) neutral helium atoms to image the surface of a sample without any …
