Abstract

Thewidespread use of phase change materials in storage media is based on the extremely rapid and reversible switching between the amorphous and crystalline phases of some families of semiconducting alloys. Detailed information about the structure of the amorphous phase and the mechanism of crystallization are essential for the development of new storage media, and we study both aspects here using density functional/molecular dynamics simulations of Ge<inf>2</inf>Sb<inf>2</inf>Te<inf>5</inf>, the prototype phase change material of the Ge/Sb/Te semiconductor family.
