Electron transport simulation in resonant-tunneling GaN/AlGaN heterostructures

A numerical method for electron transport calculations in resonant-tunneling GaN/AlGaN heterostructures has been developed on the basis of a self-consistent solution of the Schrödinger and Poisson equations. Dependences of the system's transmission coefficient on the external field and of the peak current on the ratio between the well and barrier widths have been studied for a double-barrier resonant-tunneling diode. For technical applications, the optimal values of the structure's parameters have been found.
