Electronic properties of polypyrrole/polyindene composite/metal junctions
Junction properties between conducting polymer composites of polypyrrole/polyindene
(PPy/PIn) with different conductivities and metals like Pt, Au, AI and In have been
investigated. Rectifying junctions were observed for low work function metals, In and AI;
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 …
