New Data from Columbia University Illuminate Findings in Organic Electronics (Impedance spectroscopy on copper phthalocyanine diodes with surface-induced molecular orientation)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- New research on Organic Electronics is the subject of a report. According to news reporting originating in New York City, New York, by VerticalNews journalists, research stated, "Molecular orientation and packing motif governs charge-transport property of organic semiconductor films, especially for planar small molecules. We analyze the surface-induced orientation of copper phthalocyannine (CuPc) molecules deposited on graphene or poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) covered indium-tin-oxide (PEDOT:PSS/ITO)."

The news reporters obtained a quote from the research from Columbia University, "The CuPc films deposited on graphene are templated with preferential face-on stacking, whereas the molecules on PEDOT: PSS/ITO crystallize with edge-on ordering. Static current-voltage measurement and small-signal impedance spectroscopy are combined to elucidate the structural impact on the electrical response when those films are part of a rectifying diode. The graphene-templated diode shows enhanced out-of-plane hole conduction as compared to the diode with a PEDOT: PSS/ITO contact."

According to the news reporters, the research concluded: "Equivalent circuits describing charge injection and transport properties are proposed."
