François Peeters obtained his Ph.D. in 1982 at the University of Antwerp. Subsequently, he was a postdoctoral fellow at Bell Laboratories and Bellcore (New Jersey, USA). His research interests include the theory of semiconductor and superconductor nanostructures, Wigner crystallization of bilayers and wires, and quantum confinement in nanosize superconductors. He is a member of the Editorial board of Physica B, Journal of Nanoscience and Nanotechnology, Microelectronics Journal, and Solid State Communications. Peeters is head of the research group “Condensed Matter Theory” at the University of Antwerp. He is a fellow of the American Physical Society and was recently elected by the editors of the APS journals as an “outstanding referee.”
Crystalline structures have been observed in nanoislands of electrons floating above superfluid helium. The energy required to add or subtract an electron from these quantum-dot-like islands agrees well with theory.
