摘要：
This letter focuses on the first-principles model of the photocurrent in quantum well infrared photodetectors (QWIPs) derived in reference [1]. The model explores the absorption coefficient measured experimentally. Then we move to show how the responsivity and quantum efficiency vary with a. The work in this paper shows that the device response indeed increases as QWIPs are designed and fabricated to detect longer wavelengths despite the fall in device performance as a result of the growing effect of the dark (noise) current.
