We established two evaluation methods for monolayer-order organic films on solid substrates and evaluated various kinds of films, i.e. Langmuir-Blodgett films of monoalkyl lipids, dialkyl lipids, dialkylsilane, and fluorocarbon, and chemically adsorbed films of three kinds of trichlorosilane compounds. One method is the measurement of the electroplating current during copper decoration, and the other the measurement of I-V characteristics using a micromanipulating mercury probe. Electrical characterization of the films with monolayer-order thickness is possible by using both types of liquid top electrodes, and a clear dependence of the electrical properties on monolayer number has been found quite reproducibly.
