Abstract:
According to example embodiments, a method for manufacturing a field emission cathode includes providing a liquid compound comprising a liquid phenolic resin and at least one of a metal salt and a metal oxide arranging a conductive cathode support in a vicinity of the liquid compound, and heating the liquid compound. Heating the liquid compound transforms the liquid compound into a solid compound foam.
