Mixed-Anion Mischief: Lone Pairs Meet Ionic Bonds to Suppress Thermal Transport in Quasi-1D Bi3Se4Br.
Understanding thermal transport requires exploring materials with unconventional atomic arrangements and emergent bonding motifs. Mixed-framework halogeno-chalcogenides, with their structural anisotropy and unusual bonding connectivity, provide a versatile platform for tuning lattice dynamics and transport properties....
