Transition energy as a function of current density.
Field distribution in and around the QW for different current densities.
Conduction and valance band for different current densities. Inset shows different bending of the conduction band QW.
Parameters used in the simulation. Ppz , Psp , and b are the piezoelectric polarization, spontaneous polarization, and band gap bowing parameter, respectively. V. law stands for Vegard's law.
