Do not mention material for now

\subsection{Constant Mobility}

Some materials require constant charge carrier mobility values $\mu = \textrm{const}$.

Some simulations require constant charge carrier mobility values $\mu = \textrm{const}$.

This can be simulated with this model, which can be selected in the configuration file via the parameter \parameter{mobility_model = "constant"}.

It requires the additional configuration keys \parameter{mobility_electron} and \parameter{mobility_hole} to be present in the module configuration section, for example:

\begin{minted}[frame=single,framesep=3pt,breaklines=true,tabsize=2,linenos]{ini}

# Constant mobility for electrons and holes in CdZnTe:

mobility_model = "constant"

mobility_electron = 1000cm*cm/V/s

mobility_hole = 50cm*cm/V/s
