Özet

We present a high-speed operating method with feedback to be used in dynamic atomic force microscope (AFM) systems. In this method we do not use an actuator that has to be employed to move the tip or the sample as in conventional AM setups. Instead, we utilize a Q-controlled eigenmode of an AFM cantilever to perform the function of the actuator. Simulations show that even with an ordinary tappingmode cantilever, imaging speed can be increased by about 2 orders of magnitude compared to conventional dynamic AFM imaging. (C) 2014 Elsevier B.V.
