GaAs quantum well infrared detectors with peak responsivity at 8.2 μm and significant response beyond 10 μm have been demonstrated with detectivities of 4×1011 cm (Hz)1/2 /W at 6 K; this detectivity is the highest reported for a quantum well detec

We have fabricated and characterized several GaAs/AlGaAs multiquantum well infrared detectors at temperatures ranging from 6 K to 77 K. The detectors were designed to have a single bound state in the quantum well and the first excited state in the co

The expression for the ratio between the noise current and full shot noise contained in our recent paper [J. Appl. Phys. 67, 7608 (1990)] is based entirely on standard generation‐recombination noise theory, and does not represent a more complex mod

It has been determined that anodic oxidation of (Hg,Cd)Te occurs via a dissolution‐precipitation mechanism followed by a bulk growth process which involves either interstitial transport of metal cations and/or hydroxyl anion transport via successiv

The cross section for electron photodetachment from H${\mathrm{S}}^{\ensuremath{-}}$ has been measured using an ion cyclotron resonance (ICR) spectrometer with a tunable dye laser. A cubic spline routine is employed to remove random noise from the sp

It has been determined that anodic oxidation of (Hg,Cd)Te proceeds via a dissolution– precipitation mechanism. The initial film formation can be understood in terms of electrochemical parameters and, therefore, can be controlled in a rational manne

The cross section for electron photodetachment has been measured for the thiomethoxyl anion (CH3S−) and the deuterothiomethoxyl anion (CD3S−) using an ion cyclotron resonance spectrometer in conjunction with a tunable dye laser. After accounting

This paper reports the effects of visible light and applied electric field on the properties of the HgCdTe–anodic oxide interface. The surfaces of anodized n‐type crystals are accumulated with a fixed positive charge in the oxide on the order of
