J. Voets et al., LARGE CORRUGATIONS AND STRONG ADHESION FORCES OBSERVED WITH A MECHANICALLY CONTROLLABLE BREAK JUNCTION, Physica. B, Condensed matter, 218(1-4), 1996, pp. 290-293
The observation of, often subtle, effects due to interactions between
the electrodes of a tunnel junction, requires a very stable configurat
ion. This requirement is met by a mechanically controllable break (MCB
)junction. Our measurements show clear indications of strong adhesion
forces between the two electrodes. Using the MCB in an STM-like mode,
we also found anomalously high corrugations on simple metal surfaces (
e.g. Au).
