e-mulate: a user-friendly software to calculate optoelectronic properties of quantum well systems

Abstract

We present e-mulate, an user-friendly software developed to calculate the electronic states of quantum well heterostructures. e-mulate was designed with a graphical user interface for users without previous coding skills. The unidimensional Schrödinger equation is numerically solved using transfer matrix and Numerov algorithms in the back-end. Essential figures of merit of optoelectronic devices, such as photodetectors are provided by the software: optical transition energies with their respective oscillator strengths, the absorption and the electronic transmission spectra. A comparison between the calculated absorption and experimental results of an In0.53Ga0.47As/In0.52Al0.48As quantum Bragg mirror photodetectors is presented as validation of the software.
