Fig. 4: Physics behind the breakdown pressures.
From: Robust structural superlubricity under gigapascal pressures
a Breakdown pressures calculated for metals Os, W, Re, Ni, Co, Ta, Hf, Ti, and Zr in contact with graphite. b Top-ranked features that strongly correlation with the breakdown pressure. c, d Relation between the breakdown pressure and bulk moduli (c), and the first ionization energy of the metal (d). e Bulk moduli and shear moduli of the metals. f Breakdown pressures of graphite, tungsten, and the tungsten/graphite contact. Source data are provided as a Source Data file.
