Abstract:

Field emission techniques was applied to the investigation of clean metal surfaces. In particular, the pulsed field emission microscope was used to study 1 surface migration of metal atoms over their own substrate, 2 screw dislocations, and 3 changes in emitter shape due to simultaneous application of high temperature and high electric field. Also the field ion microscope was used to investigate the atomic detail of a metal surface. Possible application of field emission to useful electronic devices was investigated in two areas 1 the development of low voltage tubes using field emission cathodes, and 2 stabilization of field emission cathodes by high current density.
