The effect of heat treatment on the morphology and mobility of Au nanoparticles

Beilstein Journal of Nanotechnology, 2020
In the present paper, we investigate the effect of heat treatment on the geometry and mobility of Au nanoparticles (NPs) on a Si substrate. Chemically synthesized Au NPs of diameter ranging from 5 to 27 nm were annealed at 200, 400, 600 and 800 °C for 1 ...

Quantitative Nanofriction Characterization of Corrugated Surfaces by Atomic Force Microscopy

, 2003
Atomic Force Microscopy (AFM) is a suitable tool to perform tribological characterization of materials down to the nanometer scale. An important aspect in nanofriction measurements of corrugated samples is the local tilt of the surface, which affects the

Suppression of material transfer at contacting surfaces: The effect of adsorbates on Al/TiN and Cu/diamond interfaces from first-principles calculations

, 2017
The effect of monolayers of oxygen (O) and hydrogen (H) on the possibility of material transfer at aluminium/titanium nitride (Al/TiN) and copper/diamond (Cu/C$_{\text{dia}}$) interfaces, respectively, were investigated within the framework of density ...

Interactive Strength between C60 Thin Film and Si(001) and Its Influence on Nano-Scaled Tribology

Tribology Online, 2008
The influences of interactions between C60 thin films and Si substrates were investigated using atomic force microscopy (AFM). It was found that higher friction coefficient was obtained at the C60 domains formed on the H-terminated Si(001) substrate and ...

Spin waves cause non-linear friction

, 2011
Energy dissipation is studied for a hard magnetic tip that scans a soft magnetic substrate. The dynamics of the atomic moments are simulated by solving the Landau-Lifshitz-Gilbert (LLG) equation numerically. The local energy currents are analysed for the
