A carrier scattering approach is taken in an analysis of the affect on the dark current of extending the operating wavelength of conventional bound to continuum quantum-well intersubband photodetectors. It is found that both the sequential tunnelling and the thermionic emission contributions to the dark current increase as the wavelength of the detector is… (More)
