TLDR
In this article, the cold cathode devices (cold cathodes) comprising electron emitting structures grown directly onto a substrate material were described. But the development of cold cathodes has not yet been considered in the field of field emission displays.Abstract:
Electron field emission devices (cold cathodes), vacuum microelectronic devices and field emission displays which incorporate cold cathodes and methods of making and using same. More specifically, cold cathode devices comprising electron emitting structures grown directly onto a substrate material. The invention also relates to patterned precursor substrates for use in fabricating field emission devices and methods of making same and also to catalytically growing other electronic structures, such as films, cones, cylinders, pyramids or the like, directly onto substrates.read more
