MULTEM: A new multislice program to perform accurate and fast electron diffraction and imaging simulations using Graphics Processing Units with CUDA
I Lobato, D Van Dyck - Ultramicroscopy, 2015 - Elsevier
The main features and the GPU implementation of the MULTEM program are presented and
described. This new program performs accurate and fast multislice simulations by including
higher order expansion of the multislice solution of the high energy Schrödinger equation,
the correct subslicing of the three-dimensional potential and top-bottom surfaces. The
program implements different kinds of simulation for CTEM, STEM, ED, PED, CBED, ADF-
TEM and ABF-HC with proper treatment of the spatial and temporal incoherences. The …
