“…Dark current measurements revealed the existence of a plateau [6] in the I(V) curves in the tunnelling regime which is attributed to the competition between the electric field localisation and the barrier lowering by the electric field [7,8]. Results are given in the last section of this paper.…”

Abstract: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 applications. Despite this reputation we demonstrate the ability of QWIP for the low infrared photon flux detection. We present the characterization of a state of the art 14.5µm QWIP from Alcatel-Thales 3-5 Lab. We developed a predictive model of the performance of an infrared instrument for a given application. The considered scene is a Cryogenic Wind Tunnel (ETW), where a specific Si:Ga camera is currently used. Using this simulation tool we demonstrate the QWIP ability to image a low temperature scene in this scenario. QWIP detector is able to operate at 30K with a NETD as low as 130mK. In comparison to the current detector, the temperature of use is three times higher and the use of a QWIP based camera would allow a huge simplification of the optical part. : 85.60Bt, 85.60Gz PACS

“…We performed a full characterization of the component (I(V), noise, differential resistance and quantum efficiency) under low flux by changing the applied bias, detector temperature and black body temperature. Dark current measurements revealed the existence of a plateau [6] in the I(V) curves in the tunnelling regime which is attributed to the competition between the electric field localisation and the barrier lowering by the electric field [7,8]. Results are given in the last section of this paper.…”

a b s t r a c tQuantum 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 applications. Despite this reputation we demonstrate the ability of QWIP for the low infrared photon flux detection. We present the characterization of a state of the art 14.5 lm QWIP from Alcatel-Thales III-V Lab. We developed a predictive model of the performance of an infrared instrument for a given application. The considered scene is a cryogenic wind tunnel (ETW), where a specific Si:Ga camera is currently used. Using this simulation tool we demonstrate the QWIP ability to image a low temperature scene in this scenario. QWIP detector is able to operate at 30 K with a NETD as low as 130 mK. In comparison to the current detector, the operating temperature is 20 K higher. The use of a QWIP based camera would allow a huge simplification of the optical part.

“…Different treatments have been applied to model the characteristics of QRIPs [6][7][8][9][10][11][12][13][14][15] . In this paper, we utilize a new simple mathematical formulation to consider the characteristics of a QRIP under dark current condition.…”

In order to study the dark current characteristics in a quantum wire infrared photodetector (QRIP), the average number of electrons in quantum wires (QRs) must be got, which is mostly too complicated. In this paper we give a simple formula to calculate the average number of carriers in a quantum wire (QR) that can be easily evaluated by mathematical softwares, and then we use this formula to study dark current characteristics of a quantum wire infrared photodetector (QRIP).
