This page gives hints on how to obtain a Scanning Tunneling Microscopy map with the ABINIT package.


The charge density of states close to the Fermi energy can be output, and provide a simple approach to STM image calculations (not for PAW). See input variable prtstm and stmbias for explanations. The example input file will also be useful. The angular momentum decomposed DOS can be evaluated in a sphere around any point, and provide STS analysis.
