In this work we present a new method of acquiring force volume data in a single scan using mixing products of different drive tones. The acquisition of such data is generally limited by the stand-by time of the system since it can easily take more than 10 hours. We address this limitation by combining our low temperature (LT) tuning fork atomic force microscopy (AFM) with two more advanced measurement methods using multiple drive frequencies and detection of up to 32 mixing products.
From the measured 32 lock-in channels we reconstruct the interaction force between the sample and the tip, resulting in a force volume measurement acquired in a single scan.
