摘要：

Medium wavelength infrared (MWIR) detectors in the 3-5 μm band are demonstrated using bound to continuum state intersubband absorption in lattice-matched InGaAs/InAlAs multiquantum well (MQW) structures. Photodetectors with responsivity peaked at 4 μm wavelength showed low dark current giving a background-limited detectivity D*BLBL =2.3×1010 cm(Hz)1/2 /W at temperatures up to 120 K.
