Lateral quantum-dot replication in three-dimensional quantum-dot crystals

Single quantum dots (QDs) reproduce into pairs of QDs with increasing separation distance during the growth of a three-dimensional QD crystal. Kinetic Monte Carlo simulations-that rely on strain profiles deduced from experiment-can describe this lateral replication process, which is triggered by a d...

Zusammenfassung:Single quantum dots (QDs) reproduce into pairs of QDs with increasing separation distance during the growth of a three-dimensional QD crystal. Kinetic Monte Carlo simulations-that rely on strain profiles deduced from experiment-can describe this lateral replication process, which is triggered by a distinct ridge structure that evolves during the overgrowth of two-dimensional periodic QD arrays.
