摘要：

Intermolecular interaction was investigated by measuring the properties of self-assembled monolayers (SAMs) in the lateral direction. We formed SAMs of octadecyltrichlorosilane (OTS) and phenethyltrichlorasilane with Ag- or Au-patterned electrodes on mica surfaces and measured the conductance under various bias voltages. Using an atomic force microscope with a conductive cantilever, we could not detect current through the SAMs in the vicinity of the electrodes about 85 nm from the edge. The resistivity of the OTS him measured using the substrates with interdigitated (comb) electrodes was strongly dependent on the humidity. From the result in a dry N-2 atmosphere, the resistivity of a SAM of OTS in a lateral direction was estimated to be similar to 9 x 10(10) Ohm cm.
