Parameter Explanation

• $N_{levels}$
• $N_{trap}$ : trap density. $c{m}^{-3}$
  
• Et : depth of trap related to Ec. $(eV)$
  
• degeneracy : degeneracy of traps, we usually set as 1.
• te : nonradiative lifetime of electrons. $(Sec.)$
  
• th : nonradiative lifetime of holes. $(Sec.)$

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
