Similarities and Differences between Two Researches in Field Electron Emission: A Way to Develop a More Powerful Electron Source

Abstract

Abstract: This paper discusses the similarities and differences between two studies that deal with resin-coated field-emission cathodes. The two works that are compared within this paper are entitled: Hot Electron Emission from Composite-Insulator Micropoint Cathodes and Methods of Preparation and Characterization of Experimental Field- Emission Cathodes. Within the text, both studies are reviewed and put into context, pointing out and commenting the advantageous features of this type of cathodes. The comparison focuses mainly on the method of preparation including deposition of a thin film on the cathode tip and the characterization of the coating itself. The effect of the coating on the field emission is discussed as well. Keywords: Cold field emission, Epoxylite 478, Epoxylite EPR-4.
