WebSep 7, 2024 · Crystal lattices are periodic structures, they have one or more types of symmetry properties, such as inversion, reflection, rotation. Table 1 summarized the … Zone axis, a term sometimes used to refer to "high-symmetry" orientations in a crystal, most generally refers to any direction referenced to the direct lattice (as distinct from the reciprocal lattice) of a crystal in three dimensions. It is therefore indexed with direct lattice indices, instead of with Miller indices. High-symmetry zone axes through a crystal lattice, in particular, often lie in the direction of tunne…

WebApr 12, 2024 · (46) The high γ indicates to the presence of strong lattice anharmonicity in TlBiSe 2 as compared to the layered tetradymites. This motivated us to look out for additional phonon scattering mechanisms unique to TlBiSe 2 that could be effective in suppressing thermal conductivity in 3D solids.
