electronic_stopping sets the option for doing a radiation cascade simulation where the electronic stopping will be taken into account and and electronic energy loss will be calculated. The force equation is modified by a friction-like term which is given as follows:
[math]\displaystyle{ \mathbf{F}_I = -\mathbf{\nabla}_IU - S_e\frac{\mathbf{v}_I}{v_I} }[/math].
The electronic stopping powers [math]\displaystyle{ S_e }[/math] are provided through an input data file, see related keyword estop_filename.
This is typically invoked while simulating collision cascades of atoms. There are three input keywords for which inputs need to be provided if this calculation is invoked. These are as follows:
eel_cut, eel_freq_out, estop_filename
Summary
| Required/optional | Type | Accepted values | Default | See also | Remarks |
|---|---|---|---|---|---|
| Optional | Boolean | .true. or .false.
|
.false.
|
eel_cut, eel_freq_out, estop_filename
|
Required functionality for simulating collision cascades |
Example
electronic_stopping = .true. eel_cut = 1.0 ! in eV eel_freq_out = 10 estop_filename = 'stopping-data-file'
