Quantum scattering engineering for the reduction of dark current in very long wavelength quantum well infrared photodetector
Emmanuel Lhuillier, Emmanuel Rosencher, Isabelle Ribet-Mohamed +3
Dark current is shown to be significantly reduced in quantum well infrared photodetectors in the tunneling regime, i.e. at very low temperature, by shifting the dopant impurity lay…
Quantum well infrared photodetectors hardiness to the non ideality of the energy band profile
Emmanuel Lhuillier, Nicolas Pere-Laperne, Isabelle Ribet-Mohamed +6
We report results on the effect of a non-sharp and disordered potential in Quantum Well Infrared Photodetectors (QWIP). Scanning electronic transmission microscopy is used to measu…
15μm Quantum well infrared photodetector for thermometric imagery in cryogenic windtunnel
Emmanuel Lhuillier, Isabelle Ribet-Mohamed, Nicolas Péré-Laperne +4
Quantum Well Infrared Photodetector (QWIP) usually suffer from a too moderate quantum efficiency and too large dark current which is often announced as crippling for low flux appli…
Interface roughness transport in THz quantum cascade detectors
Emmanuel Lhuillier, Isabelle Ribet-Mohamed, Emmanuel Rosencher +4
Infrared Detectors based on a Quantum Cascade have been proposed to suppress the dark current which is identified as a limiting factor in Quantum Well Infrared Photodetectors. Thos…
Quantum transport in weakly coupled superlattices at low temperature
E. Lhuillier, I. Ribet-Mohamed, A. Nedelcu +2
We report on the study of the electrical current flowing in weakly coupled superlattice (SL) structures under an applied electric field at very low temperature, i.e. in the tunneli…
