Abstract

Ultra-flexible and transparent metal oxide transistors are developed by doping In2O3 films with poly(vinylphenole) (PVP). By adjusting the In2O3:PVP weight ratio, crystallization is frustrated, and conducting pathways for efficient charge transport are maintained. In2O3:5%PVP-based transistors exhibit mobilities approaching 11 cm2 V-1 s-1 before, and retain up to ca. 90% performance after 100 bending/relaxing cycles at a radius of 10 mm.
