TEM from first principles
First principles simulations are invaluable aids in predicting and interpreting experimental electron microscopy images and spectra. Making use of the open source Python ecosystem, our abTEM code is the fastest and most modern simulation tool for transmission electron microscopy – and the only one built for first principles scattering potentials.
The code has seen excellent uptake by the community since its release in 2021, with significant activity on GitHub on its open-source code, and its software tool article quickly surpassing 100 citations.
Comparing typical simulated transmission electron microscopy images (ADF: annular dark-field, BF: bright-field) using abtem based on either independent atoms (IAM) or the full scattering potential (DFT) of hexagonal boron nitride (hBN) allows the influence of charge transfer to be elucidated.
