Abstract :
In this paper we introduce a new numerical method to solve drift-diffusion equations with quantum correction. Simulation results show the ability of the new method to predict quantum tunneling from potential barrier and quantum repulsion. This numerical method has the higher accuracy in comparison with the other numerical method in the same number of iteration.
