Ordered Pyramidal Quantum Dots for Quantum Photonics Applications

Semiconductor quantum dots (QDs) constitute a unique class of photonic materials, offering atomic-like spectral features in a solid-state matrix. As such, they form the basis for new systems useful for fundamental studies of quantum photonics and for novel applications in nanophotonic devices. Currently available QDs are made mostly using self-assembly techniques, yielding QD aggregates suffering from poor control on structural and spectral design. However, truly revolutionary progress in this area is expected only with QD systems with tailormade configurations and electronic structure, which will make possible quantum photonics studies and device functionalities otherwise unattainable.
