$usenewBTBT

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

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

Note: If BTBT is used. This one cannot be used.

For example:

$usenewBTBT
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.

The $usenewBTBT setting in GUI interface is here
1. After setting up the general structure, press Additional Function.
2. Check the box for BTB coefficient and fill in these fields as needed!
