The paper addresses the calculation of the band structure for different phases of the chalcogenide Ge2Sb2Te5 compound, which is raising considerable interest in view of the applications to the nonvolatile-memory technology. The band structure is necessary for determining the charge- and heat-transport properties of the material. The band diagram of the face-centered cubic phase, which is the most important one for the operation of phase-change memories, is shown for the first time.

Abstract

The paper addresses the calculation of the band structure for different phases of the chalcogenide Ge2Sb2Te5 compound, which is raising considerable interest in view of the applications to the nonvolatile-memory technology. The band structure is necessary for determining the charge- and heat-transport properties of the material. The band diagram of the face-centered cubic phase, which is the most important one for the operation of phase-change memories, is shown for the first time.
