Document Abstract
The electrical,opticalandbendingcharacteristicsofpoly(3,4-ethylenedioxythiophene)polystyrene
sulfonate (PEDOT:PSS)/Au/PEDOT:PSSdepositedonpolyethyleneterephthalate(PET)substratewere
studied asafunctionofinsertedAu film thickness.Theresultswerecomparedwiththoseofindium-tin-
oxide(ITO)andsinglelayerPEDOT:PSSelectrodes.ItwasfoundthatinsertionofAu film withoptimized
