The STEMsalabim software aims to provide accurate scanning transmission electron microscopy (STEM) image simulation of a specimen whose atomic structure is known. It implements the frozen lattice multi-slice algorithm as described in great detail in the book Advanced computing in electron microscopy by Earl J. Kirkland.

While there are multiple existing implementations of the same technique, at the time of this writing none of them is suitable for leveraging massive parallelization available on high-performance computing (HPC) clusters, making it possible to simulate large supercells and parameter sweeps in reasonable time.

The purpose of STEMsalabim is to fill this gap by providing a multi-slice implementation that is well parallelizable both within and across computing nodes, using a mixture of threaded parallelization and message passing interface (MPI).

STEMsalabim is a relatively young software package and was not heavily tested outside the scope of our group. We are glad to help you getting your simulations to run.
