Polarity-dependent Electroadhesion at Silicon Interfaces with Nanoscale Roughness
Liang Peng, Stefan Kooij, HT Ciftci +2
We measure and model electroadhesion across multi-asperity silicon interfaces with nanometer scale roughness. When electrically biased, our naturally oxidized silicon interfaces di…

The Decrease of Static Friction Coefficient with Interface Growth from Single to Multiasperity Contact
Liang Peng, Thibault Roch, Daniel Bonn +1
The key parameter for describing frictional strength at the onset of sliding is the static friction coefficient. Yet, how the static friction coefficient emerges at the macroscale…
