Crystal StructuresAn ideal crystal is constructed from an infinite repetition of identical groups of atoms• The group is known as the basis (this will contain one or more atoms)• The set of points on which the basis sits is called the lattice(a mathematical construction)Solid State Physics - Lecture 1
