In this paper, we study the intersubband impact ionization through conduction band states of quantum dot (QD) layers of an infrared photodetector. For this purpose, a photogenerated electron moving in high field active region of a p-i-n diode is assumed which can excite an electron from ground state of a QD by carrier–carrier scattering. The generated electron can escape the QD by tunneling and contribute in photocurrent giving avalanche gain to photodetector. The ionization rate and responsivity of detector are calculated from an analytical approach of intersubband transition rate equations. Results show increased responsivity in the order of several A/W.

We performed a detailed theoretical study of the electron correlation and core excitation effects on the energy distribution of the ejected electrons in the process of photon impact tunnel ionization. We used the Landau-Dykhne approach to obtain analytical formulas for the transition rate and the energy distribution with included these effects. We have limited ourselves to a non-relativistic domain, in which the rate and distribution are determined by electrical component of the laser field while the influence of magnetic can be neglected. We observed helium and helium like atoms. We have shown that the tunneling ionization mechanism may be understood as the combination of mentioned processes. We considered the case of a monochromatic wave with an elliptically polarized laser field. We compared our results with experimental and shown that ellipticity plays an important role and that inclusion of additional processes significantly influences the transition rate, as well as the energy distribution of the ejected photoelectrons.
