Abstract
A field emission device (FED) and a method for fabricating the FED are provided. The FED includes micro-tips with nano-sized surface features. Due to the micro-tips as a collection of a large number of nano-tips, the FED is operable at low gate turn-on voltages with high emission current densities, thereby lowering power consumption.
