$ifimpact_ion is a function to turn on the impact ionization. It is a field and current dependent function which will rely on the electric field in the simulation program.

The impact ionization generation rate is decided by

$G_{i m p a c t} = \frac{| J n |}{e} \times α_{n} + \frac{| J p |}{e} \times α_{p}$

$α_{n} = a_{n} * e x p (- | {(\frac{b_{n} | J n |}{\vec{E} \cdot \vec{J n}})}^{c_{n}} |)$

$α_{n} = a_{p} * e x p (- | {(\frac{b_{p} | J p |}{\vec{E} \cdot \vec{J p}})}^{c_{p}} |)$

The way to input this command is

$ifimpact_ion
 $a_{n} b_{n} c_{n} a_{p} b_{p} c_{p}$ 
 $a_{n} b_{n} c_{n} a_{p} b_{p} c_{p}$ 
 $a_{n} b_{n} c_{n} a_{p} b_{p} c_{p}$ 
 $a_{n} b_{n} c_{n} a_{p} b_{p} c_{p}$ 
...
...
...  repeat for n-layers

The $ifimpact_ion setting for 1D-DDCC in GUI interface

1.Press the Additional Functions.
2.Press the Inpact Ionization.
3.Choose you need parameters.
4.You can modify parameters in Number 4.
Number 4 correspond to $a_{n} b_{n} c_{n} a_{p} b_{p} c_{p}$
