Conductivity Measurements With Multilayered Langmuir Blodgett Films Produced By 4-Methylbenzenethiol Encapsulated Gold Nanoparticles And Two Kinds Of Peo Derivative Containing Li+ Ions

İnci Çapan


Langmuir – Blodgett (LB) thin film technique has been used to fabricate thin films of thiol-coated gold nanoparticles and lithium-doped poly(ethylene oxide) (PEO) derivative matrix. These thin films have been fabricated on interdigitated gold electrodes. Electrical measurements have been made using these thin films containing 4-32 layers. I-t measurements for all films showed that the current passing through is stable with time. The I-V measurements showed that the current passing through the Langmuir-Blodgett films is in the mA and nA (for 0-5V bias) region for nanoparticles and PEO respectively and that the presence of ions in the films modifies the conductivity.
