Abstract

Two independent strategies are presented for reducing the computation time of multislice simulations of scanning transmission electron microscope (STEM) images: (1) optimal probe sampling, and (2) the use of desktop graphics processing units. The first strategy is applicable to STEM images generated by elastic and/or inelastic scattering, and requires minimal effort for its implementation. Used together, these two strategies can reduce typical computation times from days to hours, allowing practical simulation of STEM images of general atomic structures on a desktop computer.
