Speed detection of electrons in nanoscale photodetectors Carbon nanotubes have a multitude of unusual properties which make them promising candidates for optoelectronic components. However, so far it has proven extremely difficult to analyze or influence their optic and electronic properties. A team of researchers headed by Professor Alexander Holleitner, a physicist at the Technische Universitaet Muenchen and member of the Cluster of Excellence Nanosystems Munich (NIM), has now succeeded in...

Rice University lab uses ruthenium complexes to dissolve nanotubes, add functionality A lab at Rice University has stepped forward with an efficient method to disperse nanotubes in a way that preserves their unique properties -- and adds more. The new technique allows inorganic metal complexes with different functionalities to remain in close contact with single-walled carbon nanotubes while keeping them separated in a solution. That separation is critical to manufacturers who want to spin...

Carbon nanotubes have many attractive properties, and their structure and areas of application can be compared with those of graphene, the material for whose discovery the most recent Nobel Prize was awarded. In order to be able to exploit these properties, however, it is necessary to have full control of the manufacturing process. Scientists at the University of Gothenburg are closing in on the answer. "Our results show that the metal particles that form the basis of the manufacture of...
