$usemuTfactor

$usemuTfactor is a command for user the consider the temperature dependent mobility by using a well define function instead of calling the external function.

Currently, there is only a few functions built. The format is

$usemuTfactor
Tmode a b c d

For Tmode=1,

 $T_0=a$
 $\alpha=b$
 $\mu (T) = \mu(T_0) \times ( \frac{T}{T_0} )^{\alpha}$
