Abstract: A field emission device is made by pre-activating ultra-fine diamond particles before applying them to the device substrate. This initial pre-activation increases manufacturing speed and reduces cost and reduces potential damage to the device substrate from exposure to high temperature hydrogen plasma.
A method for making an electron field emission device comprises the steps of:
   providing particles comprising diamonds;
   having said diamonds predominantly comprising diamonds having maximum dimensions in the range of 5-10,000 nm;
   exposing said particles to a plasma-containing hydrogen at a temperature in excess of 300°C;
   adhering said particles to a substrate having a conductive portion; and
   disposing an electrode adjacent said diamond particles.

Abstract: A novel and advantageous cathode structure for a field emission display apparatus is disclosed. A given pixel comprises a multiplicity of spaced apart emitter bodies (147) on a support (141). A given emitter body comprises diamond and/or rare earth boride, and has a relatively sharp geometrical feature that facilitates electron emission from the emitter body. Exemplarily the emitter body comprises in situ grown diamond, or it comprises a pre-existing diamond particle that was placed on the support. Such emitter bodies generally can be provided easily and at low cost, and typically have naturally occurring sharp geometrical features such as points and edges. We have also discovered that appropriately grown rare earth boride films of thickness 30 nm or less may substantially improve electron emission from emitter bodies, and some preferred embodiments of the invention comprise a cathode structure that comprises a thin layer of, e.g., LaB₆ on the emitter bodies. Exemplary methods of making cathodes according to the invention are also disclosed.

Abstract: A field electron emission material has a substrate (1700) with an electrically conductive surface. Electron emission sites on the conductive surface each include a layer of electrically insulating material (1703) to define a primary interface region (1702) between the conductive surface and the insulating layer (1703), and a secondary interface region between the insulating layer (1703) and the vacuum environment. Each primary interface region (1702) is treated or created so as to enhance the probability of electron injection from the conductive surface into the insulating layer (1703). Each primary interface region (1702) after such treatment or creation is either an insulator or graded from conducting adjacent the conductive surface to insulating adjacent the insulating layer (1703).
