Abstract

Self‐healing induced by structural phase transformation is demonstrated using pentacene field‐effect transistors. During the self‐healing process, the electrical properties at the pentacene interfaces improve due to the phase transformation from monolayer phase to thin‐film phase. Enhanced mobility is confirmed by first‐principles calculations.
