High Performance Polymer Nanowire Field-Effect Transistors with Distinct Molecular Orientations

Abstract

Polymer nanowires based on two diketopyrrolopyrrole conjugated polymers with similar chemical structures are shown to have distinct "edge-on" and "face-on" configurations in addition to high well-balanced hole and electron mobilities of 5.47 and 5.33 cm 2 V -1 s -1 in field-effect transistors.
