Formation of single-crystal microwires from solid films. a SEM image showing that an ultralong organic microwire crystallises from solid films with the prolonged growth time. Scale bar: 5 µm. b Optical image showing a high-density oriented microwire array. Scale bar: 400 µm. c Synchrotron radiation grazing incident X-ray diffraction of single-crystal film/microwire hybrids. More details about unit cell parameters can be found in the Supplementary Table 5. d Output characteristics of a microwire single-crystal OFET. Inset shows the polarised optical image of the device. L = 30 μm and W = 1.5 μm. Gate voltage (VGS) ranged from 10 to −95 V in −15 V steps. Scale bar: 10 μm. e Transfer characteristics with the source-drain voltage (VDS) of −50 V
