Definition of a Bravais lattice?
A(r) = A(r+T) with T = n1*a1 + n2*a2 + n3*a3 n1,2,3 are integer
What is a primitive cell?
A primitive cell fills the whole space without holes or overlapping.
All primitive cells have the same Volume and have one lattice point. (Proof it)(There are also non primitive cells which may have higher symmetry, body centered cube bcc)
is no Bravais lattice.
Graphene has a honeycomb lattice (two hexagonal lattices )It can be discribed as a hexagonal lattice with a basis of 2 atoms.
There is not only Translational symmetrie but also rotational.There are only 2, 3,4,6 fold rotation symmetries allowed (Proof it).
(5 is possible in quasi crystals)
There are which and how many Bravais lattices?
