$usetaunrbyfunc

$usetaunrbyfunc is to enable the temperature and carrier density dependent nonradiative lifetime module with the predefined function. The function is designed for each region. So if total n regions is used, then you will need to setup n regions. The format is

$usetaunrbyfunc

Type_R2  p1 p2 p3 p4 p5.....
Type_R3  p1 p2 p3 p4 p5.....

0: Use the original nonradiative lifetime defined in parameter setions
1: $\tau_{n} = p1 \times (\frac{T}{p3}) ^{p2}$ , and $\tau_{p} = \tau_{n}$
2: $\tau_{n} = p1 \times (\frac{T}{p5}) ^{p3}$ , and $\tau_{n} = p2 \times (\frac{T}{p5}) ^{p4}$
3: $\tau_{n} = p1 +  \left(\frac{P2-P1}{1+(\frac{N_{d}}{p3}) ^{p4}} \right)$ , and $\tau_{p} = \tau_{n}$
4: $\tau_{n} = p1 +  \left(\frac{P2-P1}{1+(\frac{N_{d}}{p3}) ^{p4}} \right)$ , and 
   $\tau_{p} = p5 +  \left(\frac{P6-P5}{1+(\frac{N_{d}}{p7}) ^{p8}} \right)$
