  11. Crystal Structures

    08 Jun 2010 | | Contributor(s):: David K. Ferry, Dragica Vasileska, Gerhard Klimeck

    In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a basis, a set of atoms arranged in a particular way, and a lattice. The basis is located upon the points of a lattice spanned by lattice vectors, which is an...
