Improving the structural characterization of supported on glass gold nanoparticles using Atomic Force Microscopy at vacuum

Muñoz Aguirre N., Rivera López J.E., Martínez Pérez L., Tamayo Meza P., Instituto Politecnico Nacional, MX

Surface characteristics of gold nanoparticles [1] at ambient conditions and in vacuum of the order of 10-4 Torr are compared using Atomic Force Microscopy topographic images in tapping mode. Figure 1 shows the improvement of [...]

Mechanical Nonlinear Generation with Coupled Torsional Harmonic Cantilevers for Sensitive and Quantitative Atomic Force Microscopy Imaging of Material Characteristics

Sahin O., Quate C.F., Solgaard O., Stanford University, US

Tapping-mode atomic force microscopy has been the most widely used mode of operation. Due to non-linear tip-sample forces, dynamics of the cantilever motion is an extremely rich problem. Recent studies have shown that higher harmonics [...]
