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…

On the Slipperiness of Surfactants: Charge-Mediated Friction Control at the Molecular Scale
Kaili Xie, Julie Jagielka, Liang Peng +8
From soap-covered dishes to freshly cleaned floors, surfactants can make surfaces slippery; yet, the underlying mechanism remains poorly understood. Here, we identify the molecular…
