Abstract
▶ We derive a combined model of thermionic emission and carrier drift-diffusion. ▶ The field-dependent permittivity is described by the derivative of the polarization. ▶ The space charges at the cathode interface have significant influence on the currents. ▶ The higher of barrier height is, the smaller of current densities are.
