$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 $(cm^{2}eV^{-1}s^{-1})$
• βe : electron beta $(eV^{-1/2})$
• μh : hole zero-field mobility $(cm^{2}eV^{-1}s^{-1})$
• βh : hole beta $(eV^{-1/2})$
