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
The unit of b is V/cm
The unit of a is 
Note: If BTBT is used. This one cannot be used.
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.
