electronic_stopping sets the option for doing a radiation cascade simulation where the electronic stopping and electronic energy loss will be taken into account. This is typically invoked while simulating collision cascades of atoms. The forces on atoms is given by the following equation where the second term on the right side is friction depending on the electronic stopping power:
\begin{equation}
\label{Eqn:vdependentFriction} \mathbf{F}_I = -\mathbf{\nabla}_IU - S_e\frac{\mathbf{v}_I}{v_I} \end{equation} 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 eel_freq_out = 10 estop_filename = 'stopping-data-file'
