Transistors and Light Emitters from Single Nanoclusters.
The dream of molecular electronics and optics has recently been approached by several groups working on nanochemistry. They succeeded in building a transistor from a CdSe nanoparticle synthesized by wet-chemical methods (see diagram on the right) which can operate with single electrons. In the field of optics the luminescence of single CdS and CdSe nanoparticles could be studied, which allows important conclusions about the charge carrier dynamics.
