AFM - One-line measurements - Raw Data

This raw data file contains AFM measurements acquired in PeakForce Tapping mode using a custom “one-line mode” setup, where the slow scan axis was disabled to repeatedly scan the same line. The data was collected on the sharp edge of the polymer sample, focusing on a single 20 µm line with a resolution of 1024 samples/line. A total of three consecutive scans were recorded under the following conditions: tip velocity of 20 µm/s, constant peak force of 25 nN, and excitation frequency of 2 kHz with a 100 nm oscillation amplitude. During acquisition, the relative humidity (RH) was cycled between 70% and 90%, completing approximately 5.5 cycles over the course of the measurement.
