Using the Maxwell displacement current (MDC) measurement with alternating monolayer compression and expansion process, the dielectric property of monolayers has been investigated. The monolayer expansion and compression processes were analyzed on the basis of the Debye theory, and the relaxation tim

✦ Synopsis
A modified Maxwell displacement current (MDC) measurement is described. The distance between water surface and a suspended electrode is changed sinusoidally at an angular frequency omega=omega(t), hence the MDC and the induced charge on the suspended electrode are modulated. The dc MDC current and the induced charge could be detected simultaneously and independently. This simplifies considerably charge measurements and will be helpful in the study of monolayers, e.g., the determination of the dipole moment. Copyright 2000 Academic Press.
