Parameter Explanation

$N_{l e v e l s}$
$N_{t r a p}$ : trap density. $c m^{- 3}$
Et : depth of trap related to Ec. $(e V)$
degeneracy : degeneracy of traps, we usually set as 1.
$τ_{e}$ : nonradiative lifetime of electrons. $(S e c .)$
$τ_{h}$ : nonradiative lifetime of holes. $(S e c .)$

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

Example

$multitraps
2
-1e+17  1.1  1  1.0e-7  1.0e-7 1e+18  2.1  1  1.0e-7  1.0e-7
-1e+17  1.1  1  1.0e-7  1.0e-7 1e+18  2.1  1  1.0e-7  1.0e-7
-1e+17  1.1  1  1.0e-7  1.0e-7 1e+18  2.1  1  1.0e-7  1.0e-7
-1e+17  1.1  1  1.0e-7  1.0e-7 1e+18  2.1  1  1.0e-7  1.0e-7
-1e+17  1.1  1  1.0e-7  1.0e-7 1e+18  2.1  1  1.0e-7  1.0e-7

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
