$usemunpfunc

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.

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. $(e{V}^{-1/2})$
