Abstract

Semiconducting nanowire heterostructures represent a new class of nanostructures that offer unprecedented freedom in material design. The position, diameter, composition and doping can be controlled with precision and complex structures such as core-shell and branched wires have already been demonstrated. Here we show that heterostructures in nanowires can define quantum emitters and that single spins can be addressed optically. We also present results on electrically contacted nanowires. The operation of single nanowires as light emitting diode or photodetector is demonstrated. To cite this article: V. Zwiller et al., C. R. Physique 9 (2008).

Résumé

Les nanofils semiconducteurs hétérostructurés constituent une nouvelle classe de nanostructures, qui offrent une souplesse de conception sans précédent. La position, le diamètre, la composition et le dopage de ces nanofils peuvent être contrôlés avec précision, et des structures complexes – tels que les nanofils « cœur-coquille » ou des structures arborescentes à nanofils ont déjà été réalisées. Nous montrons dans cet article la possibilité de réaliser des émetteurs quantiques, et d’adresser optiquement un spin unique confiné au sein d’un nanofil. Nous présentons par ailleurs des résultats obtenus sur des nanofils contactés électriquement. Nous montrons qu’il est possible de réaliser une diode électroluminescente ou encore un photodétecteur à partir d’un nanofil unique. Pour citer cet article : V. Zwiller et al., C. R. Physique 9 (2008).
