Transparent Organic Thin-Film Transistor with a Laterally Grown Non-Planar Phthalocyanine Channel

Authors


Abstract

An improved-performance transparent organic thin-film transistor (OTFT) is described, which has a vanadyl-phthalocyanine (VOPc) film as an active p-channel, lattice-matched (Sc0.7Y0.3)2O3 film as a high-k gate dielectric, and atomically flat indium tin oxide (ITO) film as the bottom contact (see Figure). These features—lattice matching and atomic flatness—are expected to lead to further improvements in transparent OTFTs.
