Charge transport in LB microsandwiches

It will be shown that it is possible to prepare short-circuit free LB sandwiches of a few monolayers only, if the cross sectional area is in the order of a few 10μm × 100μm. Current-voltage characteristics recorded at liquid helium temperature show distinct features like thresholds and steps which can be interpreted in terms of resonant tunneling and single electron effects. For an unambiguous assignment, however, more knowledge and better control of the organic/inorganic interface is essential.
