Abstract
Nanowire comprising an electrically conducting or semi-conducting core surrounded by an electrically insulating sheath are provided together with transducers and transistors based on these nanowires. The core of the nanowire has an average diameter of at most about 1000 nm, the nanowire has an average diameter of at most about 10 μm, and in the core, carbon nanotubes are in direct contact with each other without intervening dielectric polymer and thus form an uninterrupted conducting or semi-conducting electrical path along the length of the nanowire.
Claims60
A nanowire comprising an electrically conducting or semi-conducting core surrounded by an electrically insulating sheath,
- wherein the core comprises (preferably consists of) a plurality of carbon nanotubes and the sheath comprises (preferably consists of) a dielectric polymer,
- wherein the core has an average diameter of at most about 1000 nm and the nanowire has an average diameter of at most about 10 μm, and
- wherein, in the core, the carbon nanotubes are aligned along the longitudinal axis of the nanowire, and
- wherein, in the core, the carbon nanotubes are in direct contact with each other without intervening dielectric polymer and thus form an uninterrupted conducting or semi-conducting electrical path along the length of the nanowire.
The transducer of 40, wherein the PVDF is about 50% crystalline.
The transducer of any one of claims 37 to 76, wherein the transducer has an average diameter between about 29 nm and about 450 nm and most preferably of about 80 nm.
