Abstract(in English) Using the Maxwell-displacement-current(MDC)measurement, the dielectric relaxation and the piezoelectric properties of organic monolayers at the air/water interface were examined.The equations representing the dielectric relaxation time and the piezoelectric coefficient were derived in connection with the MDC.It was revealed that the dielectric relaxation time τ of monolayers smoothly decreases in the range of immeasurably low surface pressure as molecular area decreases, which is in good agreement with our theoretical calculation, and that the piezoelectric coefficient d_in the range where surface pressure increases by monolayer compression decreases smoothly as the molecular area decreases and reaches a constant value.
