Abstract
We have reviewed new phenomena in physics related with development of single-atom electron sources. A collimated electron beam was emitted from the single-atom situated at the top of the nano-pyramids. The following three topics have been discussed. (1) High brightness of electron beam: High-density electrons come out of the source, and overlapping of wave functions presumably produces new phenomena including anti-bunching of electrons in vacuum. Energy spectra showed characteristic features of single-atom electron sources; additional shoulders appeared in the normal spectra. 3) Stable electron emission originates from the field evaporation.
