WebThere are two steps in STEM imaging: first, the parallel electron wave is emitted by the electron gun and converged by the lens to form the convergent electron wave; second, the convergent electron wave scans the surface of sample point by point, and each sample point will get an exit wave. WebZ-contrast images are incoherent, have double the resolution of coherent images, and do not reverse contrast with focus or specimen thickness. The images represent a direct map of the scattering power at atomic resolution. There is no phase problem in an incoherent image, so it can be directly inverted to the object, avoiding the need for ...
