$usePool

The method is similar to BTBT. But one more parameters "s" is introduced. When s=-1, it will become Pool Frankel field dependent generation model.  The generation rates are decided by

$G = a \times |E|^{p} \times exp\left( - \frac{b}{|E|^{s}} \right) +a2 \times |E|^{p2} \times exp\left( - \frac{b2}{|E|^{s2}} \right)$

The unit of b is V/cm The unit of a is $cm^{-3}s^{-1}$

For example:

$usePool 
a b p s a2 b2 p2 s2
a b p s a2 b2 p2 s2
a b p s a2 b2 p2 s2
a b p s a2 b2 p2 s2
...
...
... N layers

In each layer, you will need to set the a b p coefficients. If you don't want to consider BTBT in this layer. please set a and a2 equal to 0.0.
