In the present work, a semiclassical method for calculating carrier transport and light emis- sion in a quantum well structure was designed and tested. The method developed, involves solving self-consistently the photon emission rate of the well with the capture of carriers into the well, until the condition of thermodynamic equilibrium is achieved, this being, cap- ture rate of carriers to the well equal to electron-hole recombination. It is then necessary to account for the carrier population along all the structure, and solving the Schrodinger- Poisson equation within the quantum well area. This algorithm it is solved iteratively, and utilizes the finite element software COMSOL for both the carrier transport and solving the Schrodinger-Poisson equation in the well.
