Abstract

This work focuses on the quantum mechanical evaluation of two components of the dark current in quantum well infrared photodetectors (QWIPs) - field induced emission (FIE) and thermionic emission (TE). The negligible value of the third component of the dark current - sequential tunnelling (ST) - was shown theoretically in previously published work. Calculations are on devices that cover the long wavelength - to very long wavelength-infrared (LWIR to VLWIR) region of the spectrum. The results prove theoretically for the first time various experimentally observed characteristics of these two emission components of the dark current.
