檢視 $usefieldmufunc 的原始碼

This function modifies the calculation method of mobility. 
Both electron and hole mobilities are considered electrical field-dependent terms with the default.
However, you can define this function by using [[function usefielddependent_n(indEl, matind ,Ex,Ey,T,xp,yp)]] and [[function usefielddependent_p(indEl, matind, Ex, Ey, T, xp, yp)]].<br>
The default follows the equation:<br>
:: <math>\mu=\mu_0\times exp(\beta\sqrt{F})</math>,<br>
where 
* <math>\mu</math> is the mobility,
* <math>\mu_0</math> is the zero-field mobility,
* <math>\beta</math> is the factor of the field dependence, and
* <math>F</math> is the localized electric field.
