Abstract :
In this work we present a set of computer codes based either on the finite element method or on the expansion of the Hamiltonian in a defined basis intended to help the design and the analysis of infrared photo-detectors based on semiconductor quantum wells and quantum dots. Our codes are capable of handling both arbitrary potential and effective mass profiles and they take into account the strain induced by lattice mismatch between different materials. In the present version, the computer codes allow the computation of eigenvalues, eigenvectors and oscillator strain for optical transitions. The results are presented in a graphic interface and some examples are included.
