Abstract
The present disclosure includes field emission device embodiments. The present disclosure also includes method embodiments for forming field emitting devices. One device embodiment includes a housing defining an interior space including a lower portion and an upper portion, a cathode positioned in the lower portion of the housing, a elongate nanostructure coupled to the cathode, an anode positioned in the upper portion of the housing, and a control grid positioned between the elongate nanostructure and the anode to control electron flow between the anode and the elongate nanostructure.
Claims20
A method of making a nanoscale device, comprising:
- contacting a catalyst particle on a cathode with a carbon-containing compound to produce an elongate nanostructure;
- positioning the cathode in a lower portion of a housing;
- and
- positioning an anode in an upper portion of the housing.
A method for making a field emission device, comprising:
- forming a nanotube yarn;
- coupling the nanotube yarn to a cathode;
- and
- positioning the cathode in a housing opposite an anode.
A method of making an electron tube, comprising:
- covering an entire interior surface of the electron tube with a dielectric shell;
- positioning only one single-walled nanotube in the electron tube;
- coupling a cathode to the single-walled nanotube;
- and
- positioning an anode opposite the single-walled nanotube in the electron tube, wherein the single-walled nanotube is elongate in a direction toward the anode.
