have succeeded in coupling an extremely small quantum dot with 1,000 times larger trumpet-shaped nanowire. The movement of the nanowire can be detected with a sensitivity of 100 femtometers via the wavelength of the light emitted by the quantum dot. Conversely, the oscillation of the nanowire can be influenced by excitation of the quantum dot with a laser.
A new type of atomic force microscope (AFM) uses nanowires as tiny sensors. Unlike standard AFM, the device with a nanowire sensor enables measurements of both the size and direction of forces.
For the first time, researchers at the University of Basel have coupled the nuclear spins of distant atoms using just a single electron. Three research groups from the Department of Physics took part in this complex experiment, the results of which have now been published in the journal Nature Nanotechnology.
