Donor Impurity-Related Optical Absorption in GaAs Elliptic-Shaped Quantum Dots

Figure 6

(a, b) The results are as in Figure 2, but here we are dealing with a variable height of the dot. In (a, c) the height of the dot is given by with symmetric finite confinement potentials along the -direction, whereas in (b, d) the results are for with asymmetric finite-infinite-confinement potentials along the -direction. Calculations are for , , and .
