Primitive lattice vectors - University of Michigan

For a 2D lattice, we can find twoprimitive lattice vectors (primitive translation vectors), such that any translation vector can be written as!⃗=$ %&⃗ %+$ (&⃗ (where $ %and $ (are two integers. For a 1D lattice, we can find one primitive lattice vector (primitive translation vector), such that any translation vector can be written as!⃗ ...

Tutorial 1 - Graphene

Remember that a honeycomb lattice is actually an hexagonal lattice with a basis of two ions in each unit cell. If ais the distance between nearest neighbors, the primitive lattice vectors can be chosen to be ... This is just the 2D massless Dirac Hamiltonian, which describes free relativistic electrons, where the speed of light has been ...
