Graphite basis vector
WebThe Bravais lattice of graphite is primitive hexagonal with the basis , , . Its crystalline structure consists of equidistant planes of carbon atoms, each forming a hexagonal net, stacked in a manner such that half of the carbon atoms (type A) are located directly above each other in adjacent planes, while the other half (type B) are located ...
