Multi-pass TEM simulation of graphene. (a) and (b) show the phase and amplitude of the exit wave function after a given number of passes, respectively. Simulated multi-pass phase TEM images, noise-free (c), and at various effective dose levels (d–f). The colorscale for (c–f) is in units of standard deviations from the mean intensity of each image. The scalebar is 0.14 nm.
