Atomic-resolution scanning probe microscopy experiments suffer from various problems including thermal drift, piezo nonlinearities, variability in tip apex chemistry, structural asymmetry of the tip apex, as well as tip elasticity. In this project, the effects of tip elasticity and asymmetry on atomic-resolution scanning probe microscopy experiments conducted on various model sample surfaces are investigated. Simulations conducted via analytical potentials and simple tip apex models are augmented with molecular dynamics (MD) approaches. It is projected that a better understanding of the role of the tip in scanning probe microscopy will allow more meaningful comparisons between experimental results obtained by different research groups.
