Recent studies on electron emission from diamond and related materials are reviewed. The properties of the diamond surface have been carefully investigated with well‐defined treatments and it has been confirmed that the hydrogenated diamond surface has a negative electron affinity (NEA). The field electron emission properties of a variety of carbon materials were investigated and remarkable results of high emissivity at low fields were documented. The mechanism for the low field emission was partly attributed to an NEA nature although the emission surface was not always confirmed to have NEA properties. Electron emission devices with NEA diamond surfaces have been developed. An emission device of metal‐insulator‐semiconductor structure was designed and built and its performance was investigated.
