Original Abstract

This article deals with preparation of very sharp cold field emission cathodes made from polycrystalline tungsten wire which is widely used by other researchers and manufacturers. Common manufacturing process of electrochemical etching in NaOH solution is improved by separation of electrolyte surfaces between anode and cathode. This method prevents hydrogen bubbles, formed on cathode, to fine down the electrolyte surface near anode that cause shockwaves which affect the progress of etching. Separation of surfaces leads to sharper tips of the final cathode which is the main goal of my research.
