The photonic energy bands of titanium dioxide (TiO2) hollow spherical arrays, which are self-assembled photonic crystals, were investigated. The finite-difference time domain (FDTD) method was applied to both the face-centred-cubic (fcc) and body-cen

Electronic transport in AlGaAs/GaAs THz Quantum Wells Intersubband Photodetectors (QWIPs) exhibits two different regimes separated by huge discontinuities (up to five orders of magnitude) in the resistivity. They are interpreted in terms of band stru

Photocurrent measurements have been performed on a quantum cascade detector structure under strong magnetic field applied parallel to the growth axis. The photocurrent shows oscillations as a function of B. In order to describe that behavior, we have

The Quantum Cascade Detector (QCD) is a multiple quantum well photodetector working at low bias or zero bias. It has a zero dark current occurring at 0V, together with a high photovoltaic photoresponse, since the QCD does not need any applied field t

A model of the electronic transport in a quantum cascade structure under weak illumination in a very large temperature range is proposed. In a previous work, a simple model was shown to provide an expression of the quantum cascade detector (QCD) resi

Recently phase transitions in THz Quantum Wells Inter-subband Photodetectors (QWIP) were observed. Very large current discontinuities - up to five orders of magnitude - were obtained, at low temperature [1]. Quantum well impact ionization shifts the

Performances of Quantum Cascade Detectors in the long wave infrared range (near 15 microns) will be studied for the first time. Due to their extremely low dark currents, Quantum Cascade Detectors are a promising candidate for the applications of imag
