Characterization of novel 1,3-bis-(p-iminobenzoic acid) indane langmuir-blodgett (lb) films, with and without zn2+ ions
MetadataShow full item record
Y-type 1,3-bis-(p-iminobenzoic acid) indane thin films with and without Zn2+ ions were grown by a LB technique to investigate the influence of the Zn2+ ions on their electrical properties. In this work, 1,3-bis-(p-iminobenzoic acid) indane molecules were deposited onto quartz crystal, glass and aluminium coated glass substrates, for optical and electrical measurements. A Quartz Crystal Microbalance (QCM) technique was used to monitor the reproducibility of the film growth. UV-visible spectroscopy was used to verify film deposition. From the electrical measurements, it was observed that Zn2+ ions affect the electrical properties of the LB films, by reducing the barrier height.
