Ultra fast photodetectors out of carbon nanotubes

Monday, March 7, 2011 - 13:01 in Physics & Chemistry

Single-walled carbon nanotubes are promising building blocks for future optoelectronic devices. But conventional electronic measurements were not able to resolve the ultra fast optoelectronic dynamics of the nanotubes. Now German scientists led by Professor Alexander Holleitner, physicist at the Technische Universitaet Muenchen, have found a way to directly measure the dynamics of photo-excited electrons in nanoscale photodetectors.
