$usenewBTBT

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

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

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

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.
