FIG. 1.

(Color online) For lens shaped (a) and truncated pyramidal (b) QDs, relationship of the general coordinate system to the conventional [001] coordinate system . Isotropic Tr (solid lines) and biaxial part (dashed lines) of the strain tensor for lens shaped (c) and truncated pyramidal (d) QDs. The gray surfaces in (c) and (d) represent the dots in the growth direction. (e) strain component of L3 QD in the plane demonstrating an increase of the shear strain with changing substrate orientation.

FIG. 3.

(Color online) Transition energies as they vary with the substrate orientation for lens shaped (upper panel) and truncated pyramidal (lower panel) QDs.
