Table 1 Drift and diffusion terms in Eq. (5) for two typical experimental conditions.
From: A Langevin equation that governs the irregular stick-slip nano-scale friction
Surface | Scan velocity | Normal load | Drift | Diffusion |
|---|---|---|---|---|
NaCl(001) | 13 nm/s | 3 nN | (−0.61 ± 0.02) f | (0.37 ± 0.01) f2 |
HOPG(0001) | 60 nm/s | 11 nN | (−0.38 ± 0.02) f | (0.25 ± 0.01) f2 |
