Bloch's theorem predicts partly the form of the common eigenfunctions SEMICONDUCTOR PHYSICS | … Bloch theorem. In a crystalline solid, the potential experienced by an electron is periodic. V(x) = V(x +a) where a is the crystal period/ lattice constant. In such a periodic potential, the one electron solution of the Schrödinger equation is given by the plane waves modulated by a function that has the same periodicity as that of the lattice: Bloch theorem.
