Thermionic Emission from Diamond Films in Molecular Hydrogen Environments
Diamond-based low-work function thermionic electron emitters are in high demand for applications ranging from electron guns and space thrusters to electrical energy converters. A key requirement of such diamond-based electron sources is hydrogen termination of the surfaces which can significantly reduce the emission barrier. However, at high temperatures (≤600°C), terminated hydrogen begins to ...
متن کاملBeta Radiation Enhanced Thermionic Emission from Diamond Thin Films
Diamond-based thermionic emission devices could provide a means to produce clean and renewable energy through direct heat-to-electrical energy conversion. Hindering progress of the technology are the thermionic output current and threshold temperature of the emitter cathode. In this report, we study the effects on thermionic emission caused by in situ exposure of the diamond cathode to beta rad...
متن کاملThermionic 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...
متن کاملHigh-temperature electron emission from diamond films
This work examines electron field-emission characteristics of polycrystalline diamond films at elevated temperatures. Diamond is an excellent material as a field emitter because of its exceptional mechanical hardness and chemical inertness. The motivation behind this study involves the use of field emitters in applications where high temperatures exist. Nitrogen-doped polycrystalline diamond fi...
متن کاملSecondary-electron emission from hydrogen- terminated diamond
Diamond amplifiers demonstrably are an electron source with the potential to support high-brightness, highaverage-current emission into a vacuum. We recently developed a reliable hydrogenation procedure for the diamond amplifier. The systematic study of hydrogenation resulted in the reproducible fabrication of high gain diamond amplifier. Furthermore, we measured the emission probability of dia...
