"Indentation-formed nanocontacts: An atomic-scale perspective"
Phys. Chem. Chem. Phys. (2014) in press
Abstract:
One-to-one comparisons between indentation experiments and atomistic modelling have until recently been hampered by the discrepancy in length scales of the two approaches. Here, we review progress in atomic-scale nanoindentation experiments employing scanning probe techniques to achieve depth-sensing indentation and field ion microscopy to permit detailed indenter characterization. This perspective addresses both mechanical (dislocation nucleation, defect structures, adhesion, indenter effects) and electronic (interface, disorder, and vacancy scattering) properties of indentation-formed contacts.
Congratulations to Monserratt and David – may they be happy ever after

We describe an etching procedure for the production of sharp iridium tips with apex radii of 15–70 nm, as determined by scanning electron microscopy, field ion microscopy, and field emission measurements. A coarse electrochemical etch followed by zone electropolishing is performed in a relatively harmless calcium chloride solution with high success rate.

New arcticle clarifies the interpretation of dissipation measurements in FM-AFM
posted Sep 17, 2011, 1:08 PM by Antoni Tekiel [ updated Sep 19, 2011, 8:37 AM by SPM Evaporator ]
"Our theory predicts large quantitative and qualitative variability observed in dissipation spectroscopy experiments, contrast inversion at step edges and in atomic-scale dissipation imaging, as well as changes in the power-law relationship between the drive signal and bias voltage in dissipation spectroscopy. The magnitude of apparent damping can escalate by more than an order of magnitude at cryogenic temperatures. We present a simple nondestructive method for correcting this source of apparent damping, which will allow dissipation measurements to be reliably and quantitatively compared to theoretical models."
