title = "Effect of barrier width on the performance of quantum well infrared photodetector",
abstract = "We present a study on a set of AlGaAs/GaAs quantum well infrared photodetectors with various barrier widths from about 100 to 500 {\AA}. At 77 K and for a large field-of-view (FOV) 300-K background operation, measured results on dark current, responsivity, and detectivity indicate that detectors with barrier widths larger than about 200 {\AA} have similar performance. For 60-70 K and F/2 FOV, barriers need to be larger than about 300 {\AA} to suppress inter-well tunneling.",
