Embodiments of a field emission device |
| 摘要 |
In one embodiment, the trajectory of one or more electrons is controlled in a field emission device. In another embodiment, the field emission device is configured analogously to a klystron. In another embodiment, the field emission device is configured with electrical circuitry selected to control the input and output of the device. |

1. An apparatus comprising:
a cathode; an anode, wherein the anode and cathode are receptive to a first power source to produce an anode electric potential higher than a cathode electric potential; a gate positioned between the anode and the cathode, the gate being receptive to a second power source to produce a gate electric potential selected to induce emission of a first set of electrons from the cathode; a suppressor positioned between the gate and the anode, the suppressor being receptive to a third power source to produce a suppressor electric potential selected to provide a force on an electron in a direction pointing towards the suppressor in a region between the suppressor and the anode; and at least one element arranged to at least partially determine a trajectory of each of the electrons in the first set of electrons between the cathode and the anode. |
