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

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

Setting for traps (2D) with multi-levels.

Format

$multitraps

Ntrap Et degeneracy τe1 τp1 Ntrap2 Et degeneracy  τe,2  τp,2  ... (... Repeat  Nlevels) ... NtrapN Et degeneracy  τe,N  τp,N

Ntrap Et degeneracy τe1 τp1 Ntrap2 Et degeneracy  τe,2  τp,2  ... (... Repeat  Nlevels) ... NtrapN Et degeneracy  τe,N  τp,N

Parameter Explanation

  • Nlevels
  • Ntrap : trap density. cm3
  • Et : depth of trap related to Ec. (eV)
  • degeneracy : degeneracy of traps, we usually set as 1.
  • τe : nonradiative lifetime of electrons. (Sec.)
  • τh : nonradiative lifetime of holes. (Sec.)


Note that usually τ=1Ntvthσ. 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
