Fig. 8From: Surface stress calculations for nanoparticles and cavities in aluminum, silicon, and iron: influence of pressure and validity of the Young-Laplace equationa) Difference between ΔP and the Laplace pressure for cavities as a function of the applied pressure (Blue circles: Al, green diamond: Si, red squares: Fe). The symbol size is proportional to the diameter. The surface energy of the 20 nm diameter cavity is used to calculate the Laplace pressure. b) same quantity and representation than in a), except that the diameter and pressure dependent surface stress value is now used to compute the Laplace pressure. c) Standard deviation for differences between ΔP and the Laplace pressure for cavities. Each set of bars corresponds to a specific choice for the surface energy/stress used to compute the Laplace pressure (see text for details). d): Relative difference between ΔP and the Laplace pressure for cavities as a function of the applied pressure, using the diameter and pressure dependent surface stress valueBack to article page
