Using molecular dynamics and Wigner transport theory, the authors show that thermal conductivity of amorphous HfO2 increases continuously from 50K to 2000K, driven by low-frequency vibrations and convection near the glass transition.

Thermal transport of amorphous hafnia across the glass transition
Using molecular dynamics and Wigner transport theory, the authors show that thermal conductivity of amorphous HfO2 increases continuously from 50K to 2000K, driven by low-frequency vibrations and convection near the glass transition.
