WebJul 10, 2024 · Here, we use first-principles simulations to study thermal transport in SiGe alloys and show that the effect of electron-phonon interaction on thermal transport is even more significant than that in Si because mass disorder scattering leaves long mean free path phonons behind, which are more strongly scattered by electrons. Webusing (MBE). As SiGe has a larger lattice constant than silicon, a buffer technique was employed to solve the problem by using graded SiGe in place of unstrained SiGe or strain-compensated SiGe/Si superlattice materials1,18. The thermal conductivity of the SiGe/Si superlattice is ~10 Wm-1K-1 measured by 3ω technique by Majumdar’s group in UC
