Fig. 1

a Schematic illustration of the optoacoustic transducers and the characterization system. The inset is the device structure and the cross-sectional scanning electron microscope (SEM) image of the transducer. b The simulated distribution of the acoustic field. c Experimentally measured acoustic wave (black curve) and spectrum (red curve) of the as-prepared optoacoustic transducer.
