$gaussiantraps

Function gaussian-distribution traps.

 type Nt Et σ degeneracy $\tau_n \tau_p$

Parameter Explanation

• type : type = 1 is electron trap and type = 2 is hole trap.

• Nt : total trap concerntraion. The positive and negative value is decided by type. There is no need to put (+ or -) here. For example 1.0e16 $(cm^{-3})$
  

• 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.
  

• $\tau_n$ : nonradiative lifetime of electrons. $(Sec.)$
  

• $\tau_p$ : nonradiative lifetime of holes. $(Sec.)$
  

Note that usually $\tau = \frac{1}{N_{t}v_{th}\sigma}$
