Derivation of the elementary Fowler-Nordheim equation is based on several strong physical assumptions (e.g. smooth flat surface and uniform work function across emitting surface, constant emission area and a uniform distribution of the applied field

Metal–oxide–metal (MOM) systems serving as models of supported metal catalysts, can also be used advantageously as stable field emission cathodes, provided that the external metallic layer, such as Au, is chemically “inert”. The mechanism of

The relationship between the chemical bond formation and tunneling phenomena in general, and the relationship between the field ionization of inert gases and the chemical reactivity of metallic surfaces in particular, are discussed in terms of a doub

The application of field-emission microscopy (FEM) and field-ion microscopy (FIM) to surface studies related to catalysis (symmetry of atomic-like states localized at the surface atoms of transition metals, spillover effect, dissipation of energy, et

Atomic-like states localized at individual atoms on transition metal surfaces are used for the interpretation (i) of a triangular shape of FIM images of fcc, hcp and bcc metal atoms adsorbed on a (111) plane of an fcc metal; (ii) of changes of their

The definition of the work function of a high-index plane (stepped surface) is reconsidered on the basis of FEM and FIM results. The large dispersion of experimental values of dynamic quantities is suggested to be a consequence of work function inhom
