This work presents a quantum mechanical simulation of an indium gallium nitride (InGaN) based light-emitting diode (LED) using the non-equilibrium Green's function (NEGF) method. Due to the wurtzite crystal structure, such LEDs exhibit strong polarization-induced electric fields at heterointerfaces. Standard simulation methods based on the drift-diffusion (DD) model do not take into account potentially important transport mechanisms such as quantum mechanical tunneling or non-equilibrium carrier distributions in the device. These effects are included in the NEGF model, while the semi-classical models employ parametrized approximations. In principle, the NEGF simulation therefore allows a more realistic view of the physical process that take place in the LEDs.
