FIELD EMISSION ELECTRON SOURCE AND METHOD FOR MANUFACTURING SAME

WIPO Patent Application WO/2006/126383

A1

Provided are a field emission electron source which has a high electron emission efficiency with improved electron emission performance and has excellent durability, and a field emission electron source manufacturing method for easily manufacturing such field emission electron source. In the field emission electron source, a drift layer wherein semiconductor layers and insulating layers are alternately laminated between a pair of electrodes is formed on a supporting substrate. The field emission electron source is characterized in that the semiconductor layer is composed of a metal oxide.
