STEM_CELL: A software tool for electron microscopy: Part I—simulations

The software STEM_CELL, here presented, is a useful tool for (S) TEM simulation. In particular innovative solutions are presented in (1) the supercell manipulation and parameters setting (2) simulation execution through the modified Kirkland routines (3) simulation post-processing with extended output and comprehensive graphic tools (4) image contrast interpretation through a strain channeling equation accounting for strain effects in STEM-ADF.

► The new free software STEM_CELL is presented.
► Optimal simulation parameter and crystal modeling within STEMCELL are discussed.
► Post processing HAADF simulation permits full angle/thickness/position analysis.
► Improved strain-channeling equation to predict both LAADF and HAADF features
