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. Herein, these transport coefficients of liquid Ge2Sb2Te5 at a few temperatures above melting are calculated by means of density functional molecular dynamics simulations.

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. Herein, these transport coefficients of liquid Ge2Sb2Te5 at a few temperatures above melting are calculated by means of density functional molecular dynamics simulations.
