Abstract

Field-induced infrared absorption spectra from the metal-insulator- semiconductor diodes fabricated with regioregular poly(3-hexylthiophene) or poly(3-octylthiophene) have been obtained by using a combination of infrared reflection-absorption spectroscopy and the FT-IR difference-spectrum method. The obtained spectra have been attributed to positive polarons generated at the interface with the insulator (aluminum oxide) layer in the range of minus gate voltage.
