Anything which does not strictly adhere to this definition will be considered as an "impurity". If you consider an imperfection in the lattice, it implies a crystalline defect, which breaks the perfect translational symmetry. Even the fact that the crystal has finite dimensions is such an imperfection. Imperfections in the motif arise if you dope the material, i.e. replace one atom with another kind of atom, in particular with a different electronic structure. | |
