Webb14 feb. 2024 · A crystal lattice is made of points. Principal Metallic Crystal Structures The HCP structure is a denser modification of the simple hexagonal crystal structure. Most metals crystallize in these dense-packed structures because energy is released as the atoms come closer together and bond more tightly with each other. Webb5 apr. 2012 · No - as I said the definition of hcp in LAMMPS is a sqrt (3) ratio, and you specify the a. If you want another c/a ratio then it is a custom lattice and you can use the custom option. Also you keep using "hex" in your emails, but hex is a 2d lattice in LAMMPS. Hcp is 3d. You don't need to guess about any of this.

Webb1 Yes, HCP is a simple hexagonal lattice with a basis. HCP is commonly referenced as an ABAB stacking of hexagonal close packed planes. So, the full simple hexagonal cell consists of an AB pair. The basis is a pair of atoms, one in A, and one in B. Webbhcp Since both structures are composed of stacked hexagonal layers, we expact them to be similar - and they are.
