    摘要： Systems and methods are provided for the manipulation of a polarizable object with a pair of elongated nanoelectrodes using dielectrophoresis. The nanoelectrodes can be carbon nanotubes and are coupled with one or more time-varying voltage sources to create an electric field gradient in a gap between the nanotubes. The gradient induces the movement of a polarizable object in proximity with the field. The nanotube pair can be used to trap a single polarizable object in the gap. A method of fabricating a nanoelectrode dielectrophoretic system is also provided. Applications extend to self-fabricating nanoelectronics, nanomachines, nanochemistry and nanobiochemistry. A nanoelectrode dielectrophoretic system having an extended nanoelectrode for use in applications including the self-fabrication of a nanowire, as well as methods for fabricating the same, are also provided.

    摘要： A multifinger carbon nanotube field-effect transistor (CNT FET) is provided in which a plurality of nanotube top gated FETs are combined in a finger geometry along the length of a single carbon nanotube, an aligned array of nanotubes, or a random array of nanotubes. Each of the individual FETs are arranged such that there is no geometrical overlap between the gate and drain finger electrodes over the single carbon nanotube so as to minimize the Miller capacitance (Cgd) between the gate and drain finger electrodes. A low-K dielectric may be used to separate the source and gate electrodes in the multifinger CNT FET so as to further minimize the Miller capacitance between the source and gate electrodes.

    摘要： A method and device are provided for the RF characterization of nanostructures and high impedance devices. A two-terminal electronic nanostructure device is fabricated by dividing a length of a nanostructure into a plurality of shorter, identical nanostructures using a plurality of finger electrodes electrically connected in parallel. The nanostructure may include a single walled carbon nanotube subdivided into shorter identical copies of a metallic nanotube segment by situating multiple finger electrodes along the length of the single walled carbon nanotube. Each of the subdivided shorter nanotube segments are connected in parallel. This arrangement allows for close impedance matching to radio frequency (RF) systems, and serves as an important technique in understanding and characterizing metallic (and even semiconducting) nanotubes at RF and microwave frequencies.
