Abstract: This paper presents results of groove machining of potassium niobate nanosheets using an atomic force microscope (AFM). Groove machining operations are performed using recently developed diamond coating (DC) and super sharp silicon (sss) probes. The results obtained using these probes are compared to results obtained using a conventional silicon (Si) probe in order to examine the effects of the material type and the tip radius of the AFM probe on groove machining accuracy.

Abstract: In this study, we investigated indentation behavior by varying the tip radius in a finite element model. We measured the tip radius and shape of the nano-indenter by SPM (scanning probe microscope) and compared them with the simulation results. The tip radius of cube corner indenter was measured to be 39nm, in agreement with the common tip radius of such indenters, which range from 20~50nm.
