Function for organic material. We usually assume the carrier mobility is depend on electrical field and follow Poole-Frenkel field dependent mobility equation.

Mobility follow this equation


\mu=\mu_0 exp(\beta\sqrt{E})

Where 

  • \mu_0 is the zero-field mobility
  • \beta is the factor of mobility increasing
  • E is the electric field.


Format

$usemunpfunc
1 μe βe μh βh


Parameter Explanation

\mu_n=\mu_0 exp(\beta\sqrt{E}),  \mu_p=\mu_0 exp(\beta\sqrt{E}) 
  • μe : electron zero-field mobility. (cm^{2}eV^{-1}s^{-1})
  • βe : electron beta. (eV^{-1/2})
  • μh : hole zero-field mobility. (cm^{2}eV^{-1}s^{-1})
  • βh : hole beta. (eV^{-1/2})


$usemunpfunc
11 μe βe μh βh v_{n,sat} v_{p,sat}


Parameter Explanation


  • μe : electron zero-field mobility. (cm^{2}eV^{-1}s^{-1})
  • βe : electron beta. (eV^{-1/2})
  • μh : hole zero-field mobility. (cm^{2}eV^{-1}s^{-1})
  • βh : hole beta. (eV^{-1/2})
  • v_{n,sat} saturate electron velocity (cm/s)
  • v_{p,sat} saturate hole velocity (cm/s)
 \mu_{n,temp}=\mu_0 exp(\beta\sqrt{E}),  \mu_{p,temp}=\mu_0 exp(\beta\sqrt{E}) 
 If  \mu_{n,temp} \times E > v_{n,sat}, then \mu_n = \frac{v_{n,sat}}{E} 
 If  \mu_{p,temp} \times E > v_{p,sat}, then \mu_p = \frac{v_{p,sat}}{E}
