Size dependence of (A) melting points T ( R ) /T _m and (B) Young’s modulus for Cu nanoparticles. (A) The solid lines denote predictions from our model of T(R)/T _m in terms of Equation 9, while the black triangles show the molecular dynamics simulation data. Other models [41–43] are also plotted for comparison. (B) Agreement between predictions (solid lines) and experimental observations of the size dependence of the Young’s modulus for Cu particles [43–45]. Parameters are given as r_0Cu = 0.1228 nm, σ_Cu = 1.534 N/m, Y_Cu = 128 GPa [39, 40].
