... above for Ag-PPP. The phenyl rings in the spin coated MEHPPV are expected to lie in the plane of the substrate, unlike those of PPP, where they are expected to lie perpendicular to the plane of ... charges. To summarize, spatial nonuni-formity of injection is observed for both Ag-PPP and Ag-MEHPPV interfaces. interface, assuming appropriate physical parameter values for PPP, using s...
