Four-Phonon Scattering and Phonon Coherence in Monolayer Penta-CdO2 with Ultralow Lattice Thermal Conductivity

Abstract Two-dimensional (2D) pentagonal materials have emerged as promising candidates for low-lattice-thermal-conductivity applications owing to their extraordinary geometry structures and strong intrinsic anharmonicity. However, the roles of high-order phonon scattering and ph...
