Parameter Explanation

$N_{levels}$
$N_{trap}$ : trap density. $cm^{-3}$ negative sign as electron trap and poisitive sign as hole trap
Et : depth of trap related to Ec. $(eV)$
degeneracy : degeneracy of traps, we usually set as 1.
$\tau_{e}$ : nonradiative lifetime of electrons. $(Sec.)$
$\tau_{h}$ : nonradiative lifetime of holes. $(Sec.)$
$\beta$ $Efactor$ : enhanced factor with $exp(\beta |E |^{Efactor})$

Note that usually $\tau = \frac{1}{N_{t}v_{th}\sigma}$ . Therefore, when Nt is increased, the non-radiative lifetime should decrease as well. Users need to adjust this by themselves.

Example

$fieldenhancemultitraps
2
-1e+17  1.1  1  1.0e-7  1.0e-7 1.0e-4 0.5  1e+18  2.1  1  1.0e-7  1.0e-7  1.0e-4 0.5 
-1e+17  1.1  1  1.0e-7  1.0e-7 1.0e-4 0.5  1e+18  2.1  1  1.0e-7  1.0e-7  1.0e-4 0.5 
-1e+17  1.1  1  1.0e-7  1.0e-7 1.0e-4 0.5  1e+18  2.1  1  1.0e-7  1.0e-7  1.0e-4 0.5 
-1e+17  1.1  1  1.0e-7  1.0e-7 1.0e-4 0.5  1e+18  2.1  1  1.0e-7  1.0e-7  1.0e-4 0.5 
-1e+17  1.1  1  1.0e-7  1.0e-7 1.0e-4 0.5  1e+18  2.1  1  1.0e-7  1.0e-7  1.0e-4 0.5

This means 2 trap levels. One is electron trap where the trap level is below conduction band 1.1eV. The other trap levels is hole trap levels, which is below conduction band 2.1 eV.
