electron_stop
This keyword is used to apply electron stopping forces to high-energy atoms during a run. This is usually used in radiation damage simulations.
Syntax
This keyword is used as follows:
electron_stop <file>
The first line of the file should have 3 values:
the first is the number of data points to be listed \(N\);
the second is the minimum atomic kinetic energy \(E_{\rm min}\), in units of eV;
the third is the maximum atomic kinetic energy \(E_{\rm max}\), in units of eV.
The stopping power data listed after this line should have \(N\) lines, each corresponding to one energy, which increases linearly from \(E_{\rm min}\) to \(E_{\rm max}\) with a spacing of \((E_{\rm max} - E_{\rm min})/(N-1)\). The stopping power values should be given in units of eV/Angstrom. For these \(N\) lines, the number of columns is the number of species used by the potential energy model. For a compacted multi-element NEP potential, there should be one column with the stopping power for each active species, in the active atom type order printed at initialization. For other potential models, there should be one column for each species in the order defined in the potential file.
