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).
The default follows the equation:

\mu=\mu_0\times exp(\beta\sqrt{F}),

where

  • \mu is the mobility,
  • \mu_0 is the zero-field mobility,
  • \beta is the factor of the field dependence, and
  • F is the localized electric field.

$usefieldmufunc
    1  \mu_e  \beta_e  \mu_h  \beta_h


Parameter explanation
  • \mu_e: the zero-field mobility of electron. (cm^{2}eV^{-1}s^{-1})
  • \beta_e: the factor of electron. (eV^{-1/2})
  • \mu_h: the zero-field mobility of hole. (cm^{2}eV^{-1}s^{-1})
  • \beta_h: the factor of hole. (eV^{-1/2})
