Abstract
A detailed study of direct Auger processes in 1.3 mu m InGaAsP/InP quantum wells and quantum well wires is presented. CHCC, CHLH, and CHSH Auger processes are considered, as are transitions involving confined states only, and transitions in which the excited carrier is in an unbound state of the well, with the other carriers confined. The effects of using realistic confined state wavevectors and the inclusion of evanescent tails for the confined states are examined. The approximations of Boltzmann statistics and parabolic subbands are examined, and it is found that these assumptions do not unduly affect the results (in contrast to the bulk case). A comparison of numerical results with present experimental estimates of Auger coefficients is given.
