Photoconductivity in Langmuir—Blodgett multilayer structures of phthalocyaninato-polysiloxane

The electrical and photoelectrical properties of planar photodiodes based on phthalocyaninato-polysiloxane (PcPS) are presented. Sandwich structures consisting of thin PcPS Langmuir—Blodgett films have been prepared between semi-transparent gold and aluminum electrodes. These structures possess pron...

Description
Summary:The electrical and photoelectrical properties of planar photodiodes based on phthalocyaninato-polysiloxane (PcPS) are presented. Sandwich structures consisting of thin PcPS Langmuir—Blodgett films have been prepared between semi-transparent gold and aluminum electrodes. These structures possess pronounced rectifying behavior. The photocurrent spectra exhibit peaks at 550 and 700 nm. The wavelength dependence of the photoconductivity clearly differs from the linear optical properties.
