“…During the resonance spectrum measurement, it is desirable to measure the amplitude and phase responses of the cantilever in a quasi-stationary manner at each frequency in the sweep frequency range. If the sweep rate is too fast, the measured resonance spectrum is distorted [39,40]. On the other hand, the tipsample contact conditions may vary during a sweep at each pixel if the sweep rate is too slow and the resonance spectrum measurement takes, for example, more than one second.…”

A visualization technique of subsurface features with a nanometer-scale spatial resolution is strongly demanded. Some research groups have demonstrated the visualization of subsurface features using various techniques based on atomic force microscopy. However, the imaging mechanisms have not yet been fully understood. In this study, we demonstrated the visualization of subsurface Au nanoparticles buried in a polymer matrix 900 nm from the surface using two techniques; i.e., resonance tracking atomic force acoustic microscopy and contact resonance spectroscopy. It was clarified that the subsurface features were visualized by the two techniques as the area with a higher contact resonance frequency and a higher Q-factor than those in the surrounding area, which suggests that the visualization is realized by the variation of the contact stiffness and damping of the polymer matrix due to the existence of the buried nanoparticles.
