Modeling the band to band tunneling (BTBT) with the BTBT formalism. g a e f0 p exp -b e a2 e f0 p2 exp -b2 e f0 is set as 1v cm if only a is used please set a2 0.0 b2 0.0 p2 0.0 g cm -3 s -1 a cm -3 s -1 b mv cm 
<math> G = a\times |E|^{p} \times exp\left( - \frac{b}{|E|} \right) </math>
  

<br><br>
For example: 
 $useBTBT 
 a b p a2 b2 p2 
 a b p a2 b2 p2 
 a b p a2 b2 p2 
 a b p a2 b2 p2
 ...
 ...
 ... 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 0.0
