Glass-like thermal conductivity in mass-disordered high-entropy (Y, Yb)2(Ti, Zr, Hf)2O7 for thermal barrier material

An entropy-stabilization strategy was applied to engineer a novel thermal insulating material by establishing a single-phase solid solution with the formula of (Y1/2Yb1/2)2(Ti1/3Zr1/3Hf1/3)2O7 (YYHEO). Structural analysis revealed that this material exceeded the typical substitutional solubility lim...
