Method of creating a field electron emission material and field electron emitter comprising said material

摘要

A field electron emission material is created by applying a silica precursor to graphite particles ( 11 ); processing the silica precursor to produce amorphous silica ( 12 ) which is doped and/or is heavily defective, and disposing the graphite particles ( 11 ) upon an electrically conductive surface ( 14 ) of a substrate ( 13 ) such that they are at least partially coated with the amorphous silica ( 12 ).
