WebNext we present numerical results obtained from our model, for the usual GaAs/AlGaAs QWIP structure design for detection at ∼ 8.5µm (see Ref. [16]), as well as a comparison with experi-mental data. The modelled QWIP consists of 40 periods, with well and barrier widths of 40 and 342 A, respectively and an Al content in the barrier layer of 26.3%.

WebTIRS will be the first spaceflight instrument to use QWIP arrays. A mirror controlled by a scene select mechanism will flip the field-of-view between nadir (Earth), an internal blackbody, and a deep space view for on-orbit radiometric calibration without changing the nominal earth-viewing attitude of the LDCM spacecraft ( [Irons and Dwyer, 2010] and … WebJun 4, 1998 · We propose a simple distributed model for intersubband quantum well infrared photodetectors (QWIPs), which explicitly takes into account the injecting properties of the contacts. We show that the QWIP operation with multiple QWs involves the formation of a high‐field domain near the emitter, caused by the modulation of the bound electron …
