A Lattice-Strained Organic Single-Crystal Nanowire Array Fabricated via Solution-Phase Nanograting-Assisted Pattern Transfer for Use in High-Mobility Organic Field-Effect Transistors

A 50 nm-wide 6,13-bis(triisopropylsilylethynyl) pentacene nanowire array is fabricated on a centimeter-sized substrate via a facile nanograting-assisted pattern-transfer method. Nanowire growth under a nanoconfined space adopts a lattice-strained packing motif of the NWs for strong intermolecular electronic coupling, and thus a nanowire-based organic field-effect transistor shows high field-effect mobility up to 9.71 cm(2) V-1 s(-1).
