title: Electrical and Structural Origin of Self-Healing Phenomena in Pentacene Thin Films.
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.
