21_25-26b/2009Quantum Dots: Self-Assembled Quantum Dot Molecules (Adv. Mater. 25–26/2009)

The cover shows a 2D photoluminescence intensity map from a self-assembled lateral quantum dot molecule in an electric field applied along the molecular axis. The coupling of the two quantum dots is evidenced by intricate spectral line anticrossings, indicated by dotted lines, as reported in the review by Lijuan Wang and co-workers on p. 2601. A 3D AFM image of a lateral quantum dot molecule overlapped with the ground-state electron wavefunction is shown in the inset.
