Glass‐Like Phonon Dynamics and Thermal Transport in a GeTe Nano‐Composite at Low Temperature (Small 26/2024)
Source abstract
Abstract
Microelectronics The landscape represents a GeTe-C nanocomposite, a heterogeneous medium made of materials with different elastic properties, as symbolized by mountains and valleys. A travelling phonon is scattered at the interfaces and strongly attenuated. This strong scattering, like in glasses, modifies phonon properties and leads to a low and weakly temperature dependent thermal conductivity. More in article number 2310209, V. M. Giordano and co-workers.
