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

$μ = μ_{0} e x p (β \sqrt{E})$

Where　

$μ_{0}$ is the zero-field mobility
$β$ is the factor of mobility increasing
$E$ is the electric field.

Format

$usemunpfunc
1 μe βe μh βh

Parameter Explanation

 $μ_{n} = μ_{0} e x p (β \sqrt{E})$ ,   $μ_{p} = μ_{0} e x p (β \sqrt{E})$

μe : electron zero-field mobility. $(c m^{2} e V^{- 1} s^{- 1})$
βe : electron beta. $(e V^{- 1 / 2})$
μh : hole zero-field mobility. $(c m^{2} e V^{- 1} s^{- 1})$
βh : hole beta. $(e V^{- 1 / 2})$

$usemunpfunc
11 μe βe μh βh  $v_{n, s a t}$   $v_{p, s a t}$

Parameter Explanation

μe : electron zero-field mobility. $(c m^{2} e V^{- 1} s^{- 1})$
βe : electron beta. $(e V^{- 1 / 2})$
μh : hole zero-field mobility. $(c m^{2} e V^{- 1} s^{- 1})$
βh : hole beta. $(e V^{- 1 / 2})$
$v_{n, s a t}$ saturate electron velocity (cm/s)
$v_{p, s a t}$ saturate hole velocity (cm/s)

  $μ_{n, t e m p} = μ_{0} e x p (β \sqrt{E})$ ,   $μ_{p, t e m p} = μ_{0} e x p (β \sqrt{E})$

 If  $μ_{n, t e m p} \times E > v_{n, s a t}, t h e n μ_{n} = \frac{v_{n, s a t}}{E}$ 
 If  $μ_{p, t e m p} \times E > v_{p, s a t}, t h e n μ_{p} = \frac{v_{p, s a t}}{E}$
