The introduction of Carbon Wire
Carbon Wire has top strength, ablaze weight, calefaction resistance, low accessory of thermal amplification characteristics, is capital for high-temperature boiler insulation materials, ingredients. Can be acclimated as conductive electrodes.
A carbon wire: cumulene or polyyne, bridging two-dimensional electrodes provides a archetypal for abutting atomic electronics ambit with one of the acclaimed conductive atomic wires. In the contempo experiment, the actualization of carbon wire bridging graphene bedding was empiric [PRL 102, 205501 (2009)], appropriately demonstrating a automated way of bearing the cumulene. In this work, we abstraction the structures and conductance backdrop of the carbon wire abeyant amid carbon nanotubes (CNTs) of altered chiralities (zigzag and armchair), and agnate conductance aberration aloft stretching. We acquisition the geometrical structures of the carbon wire bridging CNTs agnate to the experimentally empiric structures in the carbon wire acquired amid graphene electrodes. We appearance a adequacy to attune the conductance by alteration bridging sites amid the carbon wire and CNTs after breaking the wire. Empiric accepted accentuation via cumulene wire stretching/elongation calm with CNT alliance adherence makes it a able applicant for mechano-switching accessory in atomic nanoelectronics.
