Parameter Explanation

  • Nt : total trap concerntraion and if you wanna set n-type traps nt should be a negative value ex -9e16 vice versa (cm^{-3})
  • Et : the depth of traps central. (eV). The position of Et is decided by related position to Ec. For example, if trap is 1.1eV below conduction band, -1.1eV is used. Hole trap is using the same definition as electron trap, which is related to Ec also.
  • σ : the FWHM of trap. (eV)
  • degeneracy the degeneracy of traps we usually set as 1.
  • te : lifetime of electrons. (Sec.)
  • th : lifetime of holes. (Sec.)
