Abstract
Field emission properties of CuAlO2 nanoparticles are reported for the first time, with a low turn-on field of approximately2 V µm − 1 and field enhancement factor around 230. The field emission process follows the standardFowler–Nordheim tunnelling of cold electron emission. The emission mechanism is found tobe a combination of low electron affinity, internal nanostructure and large fieldenhancement at the low-dimensional emitter tips of the nanoparticles. The field emissionproperties are comparable to the conventional carbon-based field emitters, and thuscan become alternative candidate for field emission devices for low-power panelapplications.
