Atomically Thin Graphene Windows That Enable High Contrast Electron Microscopy without a Specimen Vacuum Chamber

15-Nov-2016 | Yimo Han; Kayla X. Nguyen; Yui Ogawa; Jiwoong Park; David A. Muller, Nano Letters, 2016

Scanning electron microscopes (SEMs) require a high vacuum environment to generate and shape an electron beam for imaging; however, the vacuum conditions greatly limit the nature of specimens that can be examined. From a purely scattering physics perspective, it is not necessary to place the ...
