A photovoltaic intersubband detector based on electron transfer on a cascade of quantum levels is presented which we called a Quantum Cascade Detector (QCD). The highest photoresponse of intersubband transition based photovoltaic detectors is demonst

La repartition de la flore Tertiaire en Afrique, três différente de l’actuelle, se comprend si on tient compte de deux facteurs essentiels: la regression des mers épicontinentales vers le nord et la dérive du continent africain. II en résulte

The transport in complex multiple quantum well heterostructures is theoretically described. The model is focused on quantum cascade detectors, which represent an exciting challenge due to the complexity of the structure containing seven or eight quan

Some parameters of integration of a Quantum Cascade Detector (QCD) in an infrared imaging system are studied. Performances of QCD are first presented : absorption and responsivity spectra, peak responsivity (around 44 mA/W), resistivity at zero bias

A photovoltaic intersubband detector based on electron transfer on a cascade of quantum levels is presented: a Quantum Cascade Detector (QCD). Optical and electrical performances of a QCD are presented: high responsivity at null bias voltage about 44

A high resistance narrow band quantum cascade photodetector (QCD) is presented. Leakage current has been suppressed, increasing the resistivity, thanks to a design in which coupling barriers have been thickened. Useless cross transitions have been el
