Electron-emission materials: New generations of emission devices are continuously being improved based on innovative materials and the introduction of physical concepts. Nanotubes, nanowires, graphene, and electron emission models are discussed in this issue, as well as original mechanisms, such as the thermoelectric effect, thermionic emission, and heat-trap processes. The cover shows a photograph of a thermoelectronic energy converter in operation and a sketch of a thermoelectronic energy converter, which shows that input energy absorbed in the top electrode (emitter) causes the emission of electrons, and are guided by a grid potential to the bottom electrode (collector). Images courtesy of R. Wanke et al. See the technical theme that appears on page 488.
