Controllable p- and n-type doping of poly[2-methoxy-5-(2′-methyl-hexyloxy)-p-phenylenevinylene] films prepared by evaporative spray deposition using ultradilute solution

Evaporative spray deposition using an ultradilute solution (ESDUS) enables polymer film preparation using diluted solution at ppm levels. We used this method for p- and n-type doping of poly[2-methoxy-5-(2′-methyl-hexyloxy)-p-phenylenevinylene] (MEH-PPV), which is a bipolar-transport polymer semicon...

Description
Summary:Evaporative spray deposition using an ultradilute solution (ESDUS) enables polymer film preparation using diluted solution at ppm levels. We used this method for p- and n-type doping of poly[2-methoxy-5-(2′-methyl-hexyloxy)-p-phenylenevinylene] (MEH-PPV), which is a bipolar-transport polymer semiconductor. The device characteristics indicated a drastic improvement of conductivity with carrier mobility. Moreover, the doping efficiency was higher than 15% in both p- and n-type doping owing to the wide dopant dispersion realized by the ESDUS technique.
