• ) studies were performed in the frequency-modulation mode [18][19]. The modulation frequency was set to 1000 Hz with a bias amplitude of 200 mV. Polycrystalline diamond-coated tips (nanosensors) with a typical radius of 20 to 70 nm were used. Frequencies for the first normal mode of the cantilever were

It is worth noting that AM is associated with force detection and FM with force gradient detection, and this difference appears

• defects. Experimental setup: dual mode NC-AFM/STM The employed scanning probe microscope, i.e., a NC-AFM in combination with a STM, was optimized for surface investigation on the atomic scale with spatial resolution of some picometers. Note that NC-AFM is frequently referred to as frequency modulation
