Tin Oxide Room Temperature Emitter Study.
Abstract
The mechanisms of activation and electron emission of tin dioxide film room temperature emitters for cold-cathode application have been investigated. The structure, composition and electrical resistivity of vapor deposited films of various thicknesses and antimony doping concentraitons have been determined. Activation and electron emission characteristics, as well as seasoning effects of room temperature emitter elements fabricated from such films have been studied. Data and information obtained have been utilized to extend previous analysis of the mechanisms involved in the activation and emission processes. Optimization of material parameters and emitter geometry for efficient and stable room temperature emission have been discussed. A new activation method using a laser beam in conjunction with an electrical current to increase the emitter area has been developed. (Author)
