    • This document relates to a method of tuning a scanning probe microscopy system and system therefore. The system comprising a sample carrier and a probe with a probe tip, and is configured for positioning the probe tip relative to a sample. The system further includes a transducer, a sensor for sensing probe tip vibrations, and a controller. The method comprises: a) applying an acoustic vibration signal comprising a first frequency and a second frequency to the sample; b) at a first position of the probe tip, controlling the transducer to sweep the first frequency across a first frequency range, and obtaining a first probe tip sensor signal; c) at a second position of the probe tip, controlling the transducer to sweep the first frequency across at least said first frequency range, and obtaining a second probe tip sensor signal; d) analyzing the first and second sensor signal to obtain a difference characteristic dependent on the first frequency, and selecting a first frequency value for which the difference characteristic exceeds a threshold for tuning the first frequency. The first and second position are selected such that a subsurface structure of the sample at the first and second position is different.

    • A scanning probe microscope is provided comprising a scanning probe (10), a holder (5) for holding a sample (SMP) in an environment free from liquid. A scanning arrangement (20) is provided therein for inducing a relative motion of the scanning probe (10) with respect to said sample (SMP) along a surface of the sample (SMP). A driver (30) generates a drive signal (Sd) to induce an oscillating motion of the scanning probe (10) relative to the surface of the sample to be scanned. A measuring unit (40) measure a deflection of the scanning probe (10), and provides a deflection signal (Sδ) indicative for said deflection. An amplitude detector (50) detects an amplitude of the oscillating motion as indicated by the deflection signal (Sδ) and provides an amplitude signal (Sa) indicative for the amplitude. The scanning probe (10) is at least partly arranged in a liquid (L) to dampen motion of said scanning probe, and therewith has a quality factor Q which is less than or equal than 5. The scanning probe (10) is accommodated in a casing (90) comprising said liquid (L), the scanning probe (10) comprising a flexible carrier (11), the flexible carrier having a movable part provided with a tip (12), which tip (12) extends through an opening (91) in said casing.
