Quantum dot necklaces and other QD chains
For the past two years, the molecular-beam-epitaxy (MBE) group at the University of Arkansas has developed a novel growth procedure to laterally line up self-assembled InGaAs quantum dots (QDs).

Quantum dots in a tube could open a new chapter in opto-electronics
Researchers in Germany managed to integrate quantum dots (QD) into the walls of nano- and microtubes. This novel structure serves as a quantum light emitter as well as optical waveguide. This represents a major step toward the realization of flexible high quality factor optical resonators based on tubes.
