Temperature dependence and size effect of thermal conductivity of Ge2Sb2Te5 thin film

This study investigates the dependence of thermal conductivity on both ambient temperature and film thickness in Ge2Sb2Te5 (GST) thin films, the most widely used phase-change material, with thicknesses under 40 nm. The measurements are performed using the thermoreflectance method, and the thermal bo...
