a Illustration of the self-healing process. b OM images and schematic of a semiconducting film cut using a surgical blade (left) and the film after healing (right). AFM height image of a semiconducting film c cut with a surgical blade and (d), after healing. e Change in the height profile of a self-healing semiconducting film for the self-healing process. f Self-healing ability of a semiconducting film, plotted as the change in the damage width as a function of time for different damage cutting sizes. g Transfer characteristics (VD = −60 V) with a cutting line (3 μm width) perpendicular to the channel as a function of the healing time. h Normalized field-effect mobilities (μ0: pristine mobility) with different cutting widths for transistors subjected to cutting perpendicular to the channel direction as a function of healing time (n = 3). i Transfer characteristics (VD = −60 V) with a cutting line (3 μm) parallel to the channel as a function of healing time. j Normalized field-effect mobilities (μ0: pristine mobility) with different cutting widths parallel to the channel direction as a function of the healing time (n = 3). All error bars were calculated using a sample in each of three batches (n = 3).
