In conclusion, the high-frequency and relatively stiff cantilever AL 3 represents an excellent choice for high-speed measurements with small amplitudes

High-speed AFM (HS-AFM) focuses on reducing imaging time to track faster dynamics than can be observed with existing instruments [25][26][27][28][29]. Where conventional AFM generates only a few images, HS-AFM generates hundreds of images
