Physical Modeling and Parameter Extraction Procedure for p-i-n Diodes with Lifetime Control

A physics-based model for diodes with lifetime control has been recently proposed. The model is an extension of a diode model that uses a Fourier series solution for the ambipolar diffusion equation in the drift region. In this paper a parameter extraction procedure for the diode with lifetime control is proposed. The procedure requires a forward characteristic and a reverse recovery measurement. The parameter extraction procedure is illustrated using finite element simulations. The physics-based model using the parameters so extracted shows excellent agreement with experimental results
