Fig. 3: Measured thermal conductivity.
From: Suppressed electronic contribution in thermal conductivity of Ge2Sb2Se4Te
a GSST thermal resistance as a function of thickness in amorphous and crystalline (annealed at 300 °C) phases. The inverse of slope for the linear fit to the experimental data corresponds to the thermal conductivity in each phase. b Thermal conductivity of as-deposited GSST with thicknesses of 20 nm (solid circles) and 220 nm (solid squares) as a function of temperature. The thermal conductivity GST (solid diamonds) is shown for comparison.
