초록

The Maxwell displacement current was generated from 4-octyl-4'-(5-carboxyl-pentamethyleneoxy)- azobenzene (denoted as 8A5H) monolayer Langmuir-Blodgett films prepared on Cr/Au-coated glass substrates due to trans-cis photoisomerization of 8A5H by application of alternate irradiation with UV light and Visible light. The displacement current was generated due to the trans-to-CIS photoisomerization by irradiation with ultraviolet light($\lambda_1$=360nm). Whereas the displacement current was generated in the opposite direction due to the cis-to-trans photoisomerization by photoirradiation with visible light($\lambda_2$=450nm). Finally, We concluded that Displacement current change according to power capacity photoirradiation, the more higher generate the more higher power capacity magnitude.
