Device structure and performance. a The preparation process for large-area flexible OTFT arrays. b Distribution of device mobility. c Typical transfer curve of the OTFT with 50 nm pentacene and a channel dimension of W = 240 μm, L = 30 μm. The gate current as a function of gate-source voltage is shown in purple. d A photograph of flexible devices for the test of bending effect. e Plots of mobility versus bending times on PET substrate based on copolymer insulating layers
