Control of Major Carriers in an Ambipolar Polymer Semiconductor by Self‐Assembled Monolayers

Selective unipolarization of an ambipolar polymer semiconductor, PNDTI-BT, by using different self-assembled monolayers, is demonstrated. For p-unipolarization, 1H,1H,2H,2H-perfluorodecyltriethoxysilane is most effective, whereas for n-unipolarization, 3-(N, N′-dimethylamino)propyltriethoxysilane is the best. Using these selective unipolarization effects, the complementary inverters based on the ambipolar polymer fabricated by a simple solution process show greatly improved switching behaviors with low power consumption.
