Carbon-carbon contacts for robust nanoelectromechanical switches.
Nanoelectromechanical devices exhibiting dramatically improved robustness through novel material selection are demonstrated. A unique combination of carbon nanotube active elements and conductive diamond-like carbon contact electrodes results in reliable switching performance not found in devices with ubiquitously-used metal thin film electrodes. This in turn represents a viable means to improv...

متن کاملPhotocurrent Amplification at Carbon Nanotube-Metal Contacts
ply a similar model. When using an electron beam instead of an ion beam, the CNTs could not be aligned, which indicates that the mass of the charge carrier is possibly involved in the process. The CNT aligned by this method maintains its elasticity, as is observed in the bending test with a nanomanipulator installed in the scanning electron microscope. Furthermore, we could obtain stable SFM im...
متن کاملCurrent-induced dynamics in carbon atomic contacts
BACKGROUND The effect of electric current on the motion of atoms still poses many questions, and several mechanisms are at play. Recently there has been focus on the importance of the current-induced nonconservative forces (NC) and Berry-phase derived forces (BP) with respect to the stability of molecular-scale contacts. Systems based on molecules bridging electrically gated graphene electrodes...
متن کاملCarbon nanotube Josephson junctions with Nb contacts
We report on the preparation of carbon nanotube Josephson junctions using superconducting electrodes made of niobium. Gate-controllable supercurrents with values of up to 30 nA are induced by the proximity effect. The IV curves are hysteretic at low temperature and the corresponding switching histograms have a width of 0.5%–2%. An on-chip resistive environment integrated in the sample layout is...
