WebApr 12, 2024 · Metavalent bonding has attracted immense interest owing to its capacity to impart a distinct property portfolio to materials for advanced functionality. Coupling metavalent bonding to lone pair expression can be an innovative way to propagate lattice anharmonicity from lone pair-induced local symmetry-breaking via the soft p-bonding … WebIn addition, the performance of the phonon group velocity, phonon anharmonicity, and scattering channel shows that the ultra-low k l of the novel 2D TlInSe 3 is attributed to the stronger phonon anharmonicity, lower phonon group velocity, and the scattering interaction of ZA + O→O, TA + O→O, and LA + O→O process. In addition, the weak Tl ...
