Bozkurt, A.Ercelebi, C.Toppare, L.2016-02-082016-02-0819970379-6779http://hdl.handle.net/11693/25642Junction properties between conducting polymer composites of polypyrrole/polyindene (PPy/PIn) with different conductivities and metals like Pt, Au, Al and In have been investigated. Rectifying junctions were observed for low work function metals, In and Al; however, high work function metals, Pt and Au, were observed to form ohmic contacts to PPy/PIn composite in the sandwich geometry. The rectifying behavior of the metal/composite/Pt junctions improved when the conductivity of the composite was decreased from 1 to 0.01 S/cm. Using the ideal Schottky theory various junction parameters have been determined. All planar junctions were ohmic regardless of the conductivities of the samples.EnglishComposite/metal junctionsAluminumAromatic polymersConductive filmsCurrent voltage characteristicsElectric conductivity of solidsElectronic propertiesGoldIndiumOrganometallicsPlatinumPolyolefinsSchottky barrier diodesCapacitance voltage characteristicsPolyindenePolypyrroleConductive plasticsArticle10.1016/S0379-6779(97)80112-9
