Colloquium

Mechanical resonators based on nanotubes and graphene

Wednesday, 11 February 2015, 16:30-18:00
Talk given by Prof. Adrian Bachtold IFCO – The Institute of Photonic Sciences Castelldefels (Barcelona), Spain Abstract: Carbon nanotubes and graphene offer unique scientific and technological opportunities as nanoelectromechanical systems (NEMS). Namely, they have allowed the fabrication of mechanical resonators that can be operable at ultra-high frequencies and that can feature high quality factors. In addition, nanotubes and graphene have exceptional electron transport properties, including ballistic conduction over long distances. Coupling the mechanical motion to electron transport in these remarkable materials is thus highly appealing. Here, I will review some of our recent results on nanotube and graphene resonators, including mass sensing at the proton mass level [1], force sensing with ~10 zN/Hz1/2 noise [2], and the measurement of quality factors up to 5 million [3].
