Anomalous improved electron field emission from hybridised graphene on Mo tip arrays

A new, efficient electron field emitter geometry, based on monolayer graphene coated well aligned Mo tip arrays, is here reported. The rather anomalous, yet nonetheless beneficial contributions of this hybridized nanostructured film morphology is evaluated and discussed. Efficient and stable field emission with low turn on fields has been observed. Incorporation of graphene and Mo tip array results in noteworthy improvements in emission of these nanoscale heterostructure devices.
