Thermionic emission from surface-terminated nanocrystalline diamond

Thermionic electron emission forms the basis of both electron sources for a variety of applications and a direct energy conversion process that is compact and scalable. The present study characterizes thermionic emission from boron-doped nanocrystalline diamond films with hydrogen and nitrophenyl surface termination layers. A hemispherical energy analyzer was used to measure electron energy dis...

Thermionic emission from defective carbon nanotubes

Using a nanomanipulation system contained within a scanning electron microscope we investigate the thermionic electron emission from multiwall carbon nanotubes. Peak emission currents of 65 nA are measured. The carbon nanotubes being grown at low temperature by the chemical vapor deposition method are defective with poor thermal conductivity. We believe it is crucial for the thermal conductivit...

Photo- and thermionic emission from potassium-intercalated carbon nanotube arrays

Carbon nanotubes CNTs are promising candidates to create new thermionicand photoemission materials. Intercalation of CNTs with alkali metals, such as potassium, greatly reduces their work functions, and the low electron scattering rates of small-diameter CNTs offer the possibility of efficient photoemission. This work uses a Nd:YAG YAG denotes yttrium aluminum garnet laser to irradiate singlean...
