Composition makes a structure. Atoms arrange into lattices, phases, grains, surfaces, and defects rather than one abstract material.

propertytransport
A more ordered lattice and fewer defects can make charge transport more coherent; the band gap helps classify the material's electrical response.
The lattice and band diagram are linked by a teaching model. Real materials also depend on composition, crystal structure, temperature, grain boundaries, and measurement direction.
