Thermodynamics of the System Ag2se-Ag2s: A Molecular Dynamics Study

  • Published:
MRS Online Proceedings Library Aims and scope

Abstract

We report on Molecular Dynamics (MD) studies of free energy and vibrational entropy differences of the binary system Ag2Se-Ag2S as function of temperature. We have employed the methods of adiabatic switching and temperature integration over a reversible path to obtain the phase diagram. We discuss the nature of the entropy difference in terms of ion mobility and previous MD calculations of diffusion rates in these systems.
