摘要：
A unipolar self-consistent numerical model, based on the drift-diffusion equation, for a metal/organic semiconductor/metal structure is presented. It includes electric field- and carrier density- dependent mobility. The boundary conditions are based on the continuity of the displacement field and electrochemical potential in the whole device. For the metal regions, using Thomas-Fermi approximation, analytical expressions for the electric field are obtained. In the semiconductor region the equations are approximated by finite-difference schemes.
