Ultralow Lattice Thermal Conductivity in Complex Structure Cu26V2Sn6Se32 due to Interaction of Low-Frequency Acoustic-Optical Phonons
Kewal Singh Rana, Debattam Sarkar, Nidhi +4
Damping of phonon momentum suppresses the lattice thermal conductivity (kl) through low energy acoustic-optical phonon interactions. We studied the thermal transport properties and…
