Non-contact atomic force microscopy study of hydroxyl groups on the spinel MgAl2O4(100) surface.
Atom-resolved non-contact atomic force microscopy (NC-AFM) studies of the magnesium aluminate (MgAl(2)O(4)) surface have revealed that, contrary to expectations, the (100) surface is terminated by an aluminum and oxygen layer. Theoretical studies have suggested that hydrogen plays a strong role in stabilizing this surface through the formation of surface hydroxyl groups, but the previous studie...
متن کاملEffective Parameters in Contact Mechanic for Micro/nano Particle Manipulation Based on Atomic Force Microscopy
The effect of geometry and material of the Micro/Nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. Hertz contact model simulation for EpH biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. Then, to val...
متن کاملNon-contact Friction Force Microscopy Exploiting Lateral Resonance Enhancement
A method for sensing the dissipation occurring when a sharp atomic force microscopy (AFM) tip is oscillated laterally above a surface at distances typical of non-contact mode AFM operation is established and demonstrated. Dissipation is detected by measuring the damping of lateral resonant modes of the AFM cantilever, excited independently after the lateral resonant mode identification, when th...
متن کاملContact-resonance atomic force microscopy for viscoelasticity
We present a quantitative method for determining the viscoelastic properties of materials with nanometer spatial resolution. The approach is based on the atomic force acoustic microscopy technique that involves the resonant frequencies of the atomic force microscopy cantilever when its tip is in contact with a sample surface. We derive expressions for the viscoelastic properties of the sample i...
متن کاملResolving Intra- and Inter-Molecular Structure with Non-Contact Atomic Force Microscopy
A major challenge in molecular investigations at surfaces has been to image individual molecules, and the assemblies they form, with single-bond resolution. Scanning probe microscopy, with its exceptionally high resolution, is ideally suited to this goal. With the introduction of methods exploiting molecularly-terminated tips, where the apex of the probe is, for example, terminated with a singl...
