摘要

Field emission devices are configured in addressable arrays.

主权项

1. An apparatus comprising:
an array of field emission devices, each field emission device in the array of field emission devices 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 electron emission from the cathode; anda 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 circuitry operably connected to the array of field emission devices to control an output of the array.
