This Special Topic Collection is in conjunction with the 34th International Vacuum Nanoelectronics Conference, IVNC 2021, being held virtually on July 5-9, 2021. This collection is devoted to the nanoscience and technology of vacuum electron sources and their applications, and contains material from papers presented at IVNC 2021 as well as research articles that are on these topics but were not presented at the conference.
Topics covered include, but are not limited to:
- Emitters – Nano and micro vacuum field emitters, including integrated micro fabricated tips and novel emitters such as nanotubes, graphene, nanowires, etc.
- Applications – Vacuum nanoelectronics applications including displays, x-ray imaging, electron and light sources, vacuum microdevices, electron lithography for advanced semiconductor fabrication, etc.
- Theory – Electron emission theory, including ab initio and classic tunneling approaches.
- Modeling – Modeling and simulation of electron emission physics from surfaces and devices, including microtips, nanogaps, photoemission, etc.
- Fundamental – Fundamental studies of electrons in vacuum related to beam physics, quantum mechanics, coherence, electron-photon interactions, etc.
- Microscopy and Spectroscopy – Vacuum nanoelectronics for enabling microscopy and spectroscopy, including, for example, ultimate electron microscopy and holography and scanning field emission microscopy.
- Novel emitters – Emitters based on novel electron emission mechanisms such as metal insulator metal planar emitters.
- Fabrication – Materials, growth, and fabrication technologies of sources and vacuum electronic devices.
- Ultrafast – Ultrafast laser excitation of electron emission from surfaces, tips, and nanomaterials.
- RF to THz – Novel strategies for RF and THz generation related eventually to FE sources.
- Large instruments – Accelerator beam physics.
- Vacuum technologies – Novel enabling technologies for electron sources and applications such as special electronics, vacuum generation and retention, beam imaging devices and strategies, phosphors, etc.
- Related emission – Though not the main thrust, reviews on thermionic emission, photoemission and RF/THz tubes from our sister organizations would be welcome to complement this work.
