abTEM: transmission electron microscopy from first principles

Docs | Install Guide | Walkthrough

abTEM (pronounced "ab-tem", as in "ab initio") provides a Python API for running simulations of (scanning) transmission electron microscopy images and diffraction patterns using the multislice or PRISM algorithms. It is designed to closely integrate with atomistic simulations using the Atomic Simulation Environment (ASE), and to directly use ab initio electrostatic potentials from the high-performance density functional theory code GPAW. abTEM is open source, purely written in Python, very fast, and extremely versatile and easy to extend.

Installation

You can install abTEM using pip:

$ pip install abtem

For detailed instructions on installing abTEM, see the installation guide.
