Abstract
Thermoelectric effects play an important role in the programming operations of phase change memories. The electrothermal modeling of the device thus requires the knowledge of transport coefficients such as the electrical and thermal conductivities and the Seebeck coefficient at different temperatures. In this work, we calculate the transport coefficients of liquid Ge 2 Sb 2 Te 5 at temperatures above melting by means of density functional molecular dynamics simulations.
