Parameter Explanation

  • N_{levels}
  • N_{trap} : trap density. cm^{-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.)


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
