A modulated field emission from carbon nanotubes cold cathode cavity resonator in L band frequency


A re-entrant cavity resonator with carbon nanotubes cold cathode was fabricated. The cold cathode was driven by L band signal and a modulated electron emission of CNTs was achieved. An average current of 3.865 &#x03BC;A was recorded when a 1W/1.572GHz signal was led in the cavity, corresponding density of 193.3 &#x03BC;A/cm<sup>2</sup>. The highest output… (More)
