摘要：

The thermal and electrical properties in the (Ge:Sb:Te) system have been determined using photoacoustic and Hall measurements, respectively. The thermal diffusivity, thermal conductivity, hole concentration, and Hall mobility are analyzed as a function of the tellurium concentration in the bulk alloys. It is found that both the thermal and electrical parameters depend strongly on the alloy composition and on the crystalline structure of the solid compound. The thermal and electrical measured parameters correlate well with the density of holes arising from Ge and/or Sb vacancies.
