Analysis of the occurrence of stick-slip in AFM-based nano-pushing

The use of the Atomic Force Microscope (AFM) as a tool to manipulate matter at the nanoscale is promising. However, the complexity of the corresponding physics and mechanics makes such nanomanipulation difficult and not very accurate. In the present paper, we analyze the dynamics of AFM-based nano-p...

Description
Summary:The use of the Atomic Force Microscope (AFM) as a tool to manipulate matter at the nanoscale is promising. However, the complexity of the corresponding physics and mechanics makes such nanomanipulation difficult and not very accurate. In the present paper, we analyze the dynamics of AFM-based nano-pushing manipulation. Simulation results show that the choice of the manipulation speed and loading force highly affect the manipulation outcome. In addition, simulations predict the existence of several threshold manipulation speeds. These thresholds mark the transitions between no stick-slip motion and either unique or multiple coexisting stick-slip. The obtained results bear significant implications and help get more insight into AFM-based nano-pushing.
