In this work we evaluate different dark current models applied in QWIPs. In order to avoid empirical parameters we calculate the sequential tunneling probability of the lowest energy state to reproduce the dark current properties. Using the same argu

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 quantu

A study of magnetotunnelling in weakly coupled multi-quantum wells reveals a new phenomenon which constitutes a kind of memory effect in the sense that the electrical resistance of the sample after application of the magnetic field is different from
