Abstract
A field emission cathode device and method for forming a field emission cathode device involve a cathode element having a field emission surface disposed in spaced-apart relation to a gate electrode element so as to define a gap between the field emission surface and the gate electrode element. The gate electrode element extends laterally between opposing anchored ends. The gate electrode element is arranged to deform away from the field emission surface in response to heat, so as to increase the gap between the field emission surface and the gate electrode element.

A field emission cathode device, comprising:
- a cathode element having a field emission surface;
- and
- a gate electrode element disposed in spaced-apart relation to the field emission surface of the cathode element so as to define a gap therebetween, the gate electrode element laterally-extending between opposing anchored ends, the gate electrode element being arranged to deform away from the field emission surface in response to heat, so as to increase the gap between the field emission surface and the gate electrode element.
A method of forming a field emission cathode device, comprising:
- arranging a gate electrode element in spaced-apart relation to the field emission surface of the cathode element so as to define a gap therebetween;
- and
- anchoring opposing ends of the gate electrode element such that the gate electrode element extends laterally therebetween, and such that the gate electrode element is arranged to deform away from the field emission surface in response to heat, so as to increase the gap between the field emission surface and the gate electrode element.
