Temperature-dependent thermal conductivity of Ge2Sb2Te5 polymorphs from 80 to 500 K
Journal of Applied Physics, Volume 133, Issue 13, April 2023. We report the thermal conductivity of amorphous, cubic, and hexagonal Ge2Sb2Te5 using time-domain thermoreflectance from 80 to 500 K. The measured thermal conductivities are 0.20 W m−1 K−1 f…
