In this work we developed computational routines in Python for the calculation of the dynamic properties (spectrum of photocurrent and absorption) of semiconductor heterostructures based on Quantum Dynamics Theory. In a first stage of the development of the project the formulation based on the time evolution of the solutions of the time dependent Schrödinger equation was applied to systems with known analytical solutions or results already reported in the literature. Due to the excellent agreement between our data and those already known, in the next stage the transition energies observed in photoluminescence spectra for InGaAs/GaAs quantum wells, grown by MBE, were calculated taking into account the effects of stress and segregation of indium atoms. In the continuity of the project, special attention was given to the development of strategies to calculate absorption and photocurrent spectra for solid state devices. The set of results presented in this work demonstrates that the methodology developed is accurate and can be used with low computational cost for the modeling of more complex semiconductor heterostructures, which are used for the development of optoelectronic devices.
