Automated Rotating TEM Simulations of Graphitic Material Vanessa Angenent, Rochus Schmid

Abstract

The simulation of TEM images is computationally difficult. However, in the limit of completely amorphous materials, it can be simplified to the mass-thickness contrast only, neglecting any diffraction. Our method allows fast creation of TEM images of char models and allows to find an optimal viewing angle. The intention of our char models is to investigate the stacking and bending of graphitic carbon systems. To count the planes of a stack and determine the plane length and curvature one needs specific angles to create the TEM image. A good angle gives a high contrast between carbon layers. In this paper, we show TEM simulations of four different carbon structures.
