DC Conductivity of Platinum From Ab Initio Simulation

Platinum (Pt) is a highly unreactive transition metal with a high melting point. Alongside its everyday uses, Pt’s properties make it desirable for high pressure shock experiments at Sandia National Laboratories’ (SNL) Z Pulsed Power facility. Previous literature [Earth Planet. Sci. Lett., 544 (2020), p. 116380] have reported electrical conductivity values for Pt at ambient pressure near the melting point. Here we present Kubo Greenwood (KG) electrical conductivity convergence studies for Pt at ambient conditions, as well as a comparison of the conductivity at temperatures near Pt’s melt with those reported. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525.
