Heterojunction Tunneling

Application ID: 65761

This benchmark model simulates a graded heterojunction using the thermionic emission formulation for the charge transfer over the junction. It shows the additional contribution to the current density from the quantum tunneling effect across the potential barrier, using the WKB approximation. Even though the simulated system is 1D in nature, a 2D model is created to illustrate the procedure for simulating a more general configuration. Also demonstrated is the setup of user-defined ternary material properties. The computed I-V curves, their temperature dependence, and energy band diagrams all agree well with results from the literature.

This model example illustrates applications of this type that would nominally be built using the following products:
