Single-Crystalline GdB Nanowire Field Emitters.
The article presents information on single-crystalline nanowire field emitters. Rare-earth hexaborides are the best thermionic electron sources due to their low work function, low volatility at high temperature, high conductivity, high chemical resistance, and high mechanical strength. Single-crysta...

Rare-earth hexaborides are the best thermionic electron sources due to their low work function, low volatility at high temperature, high conductivity, high chemical resistance, and high mechanical strength. Single-crystallines ye shown this advantage in thermionic electron emission applications during the past 50 years. A field emission electron source offers a brightness more than 100 times higher than the conventional thermionic electron sources, and its current density J can be expressed by the Fowler-Nordheim equation . pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2005 holdings: @attributes: islocal: N |
