Carbon nanotubes (CNTs) are a unique form of carbon filament/fiber in which the graphene walls roll up to form tubes. They can exhibit either metallic-like or semiconductor-like properties. With the graphene walls parallel to the filament axis, nanot

This paper describes a novel photocathode which is an array of vertically aligned multi-walled carbon nanotubes (MWCNTs), each MWCNT being associated with one p-i-n photodiode. Unlike conventional photocathodes, the functions of photon-electron conve

We present a fully elaborated process to grow arrays of metallic nanowires with controlled geometry and density, based on electrochemical filling of nanopores in track-etched templates. Nanowire growth is performed at room temperature, atmospheric pr

The combination of high frequency, high power, high efficiency capabilities is a feature of vacuum tube technology. For most of applications, large bandwidths are required, and therefore the modulation method should also allow large bandwidth operati

Cold cathodes based on carbon nanotubes allow to produce a modulated electron beam. Using an array of vertically aligned CNs that exhibit an aspect ratio of about 200, we demonstrated the modulation of a high current density beam (~ 1 A/cm2 at 1.5 an

We have demonstrated for the first time a beam modulation at 1.5 GHz (Teo, et. al., 2005). However, the use of resonant cavities leads to narrow bandwidth operation. To overcome this limitation we propose an optical control of the electron beam modul

Field emission measurements on individual carbon nanotubes grown by dc plasma CVD at 700/spl deg/C have been performed with a high resolution scanning anode field emission microscope. I-V characteristics of as-grown CNs show a saturation for currents

A micro-triode operating at 30 GHz is currently under development. This triode is composed of two 30 GHz re-entrant resonant cavities (input and output, respectively cathode-grid space and anode-grid space) separated by a grounded thin metallic grid.

When a carbon nanotube emitter is operated at high currents (typically above 1 microA per emitter), a small voltage drop ( approximately few volts) along its length or at its contact generates a reverse/canceling electric field that causes a saturati

Most long-range telecommunication systems are based upon microwave links. The transmitters use microwave amplifiers which in the very near future will be required to work at up to 30–100GHz with output power in the region of a few tens of watts. Ca
