Development of Field Emission Device with Tungsten Nanowires

Abstract

Tungten oxide nanowires are promising material for a field emitter because of their high aspect ratios and easy fabrications. In this paper, we studied the condition to get good tungsten oxide nanowires with best emission ability for field emitters.We decided that the best condition to get tungsten nanowires for field emitters is at a temperature of 800°C in an argon–hydrogen atmosphere about 45 Pa.
