Bulk Amorphous Alumina: The Density-Driven Interplay of Pentahedral Pyramids and Octahedra for High Dielectric Permittivity
. Our newly proposed synthesis method, which achieves an anomalous matrix formed by the density-driven interplay of pyramids and octahedra, has the potential to pave the way for the creation of a wide range of novel bulk amorphous materials without glass-forming ability, exhibiting excellent physicochemical properties.
