Since the stoichiometry of the salt is 2:1, we must fill all of the tetrahedral holes (the FCC structure gives four selenides, thus we need eight lithiums). will occupy the latice points that define ...

Scientists studying a promising quantum material have stumbled upon a surprise: within its crystal structure, the material naturally forms one of the world's thinnest semiconductor junctions—a ...

A bizarre "Rule of Four" has been identified in the basic structure ... a conventional unit cell (a larger cell than the primitive one, representing the full symmetry of the crystal) is ...

A low-magnification plan-view HAADF images of a two-unit-cell freestanding STO film transferred ... and they exist in a number of crystal structures including rhombohedral-like, tetragonal-like, ...

This picture shows the crystal structure of the superconducting film ... with the modulation period spanning several unit cells. However, the pair density modulation within single unit cell ...
