We demonstrate the first long-wave, room temperature II-VI materials based Quantum Cascade emitter around 7.2 μm. At 80 K, a device differential resistance of 2.6 Ω and a narrow electroluminescent width of 16% was obtained.
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 2×109 cm√Hz/W.
