Conventional 3D electron microscopes rely on emission, focusing, deflection, and detection of a focused beam of ballistic electrons to analyse the structure and composition of materials. Here, the authors examine the analogous concept of a 2D electron microscope based on graphene ballistic Dirac electrons.
