Abstract

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.
