| Summary: | This paper is an experimental investigation of the major implications brought in the crossing
resistance of mechanically contacted metals when operating in the high electronic injection
regime, i.e., steady state interfacial voltage values greater than the max. acceptable level
determined by specifications and less than the melting voltage. Under such operating conditions,
monolayers of positive ions may be formed within interfacial cavities filled by the
material from the surrounding space. The dominating ion neutralization process on the cathode
controls the formation of “Helmholtz” inner layers at the metal cathode+oxide+gas
interface. The presence of a positive ion monolayer over the cathode electrode will tend to
reduce the field threshold required for electronic field emission and affect the overall currentvoltage
characteristics. |
