We have studied two different kinds of electron tubes using a cold field emission cathode as the electron source. This cathode is an array of vertically aligned multiwall carbon nanotubes. The first device is a triode. With this device, we demonstrat

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

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.

Carbon nano-tubes are alternatives to conventional metal/silicon tips for field emission sources. They exhibit extraordinary field emission properties because of their high electrical conductivity, their high aspect ratio "whisker-like" shape for opt

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

To communicate, spacecraft and satellites rely on microwave devices, which at present are based on relatively inefficient thermionic electron sources that require heating and cannot be switched on instantaneously. Here we describe a microwave diode t

Using plasma treatments at 400C we have performed hydrogenation (and deuteration) of amorphous silicon films grown by thermal decomposition of silane (CVD). Diffusion profiles have been measured on deuterium using SIMS and checked by nuclear reaction
