Definition of lattice for Students. 1  1 : a structure made of thin strips of wood or metal that cross each other. 2  2 : a window or gate having a lattice.
A lattice that can be characterised in this way is referred to as a Bravais lattice. [2] All lattice points are equivalent, i.e. all properties remain invariant under translations by any vector âTmno. Also, an observer sitting on one specific lattice point would see the same environment as when sitting on any other.
