Room temperature and high responsivity short wavelength II-VI quantum well infrared photodetector

We experimentally demonstrate a short wavelength ZnCdSe/ZnCdMgSe quantum well infrared photodetector (QWIP) with a room temperature responsivity of over 30 A/W. The dark-current limited detectivity at 80 K was measured to be 2×10
