(a) Device configuration using a bottom-contact structure. The PII2T-Si is spin coated on a silicon wafer with a SiO2 dielectric layer and previously evaporated gold electrodes of channel width (w) and length (l) (not to scale). (b) Surface morphology of the fabricated OFET measured with an atomic force microscope operated in tapping mode. Scale bar, 1 μm. (c) Optical image of a fabricated OFET on flexible substrate with a PDMS flow cell. Flow direction of the liquid is indicated by the black arrows. Scale bar, 1 cm.
