According to Bloch’s theorem, the wave function solution of the Schrödinger equation when the potential is periodic and to make sure the function u (x) is also continuous and smooth, can be written as: Where u (x) is a periodic function which satisfies u (x + a) = u (x).


as the Bloch theorem forms the foundation on which the rest of the course is based. 2.2 Introducing the periodic potential We have been treating the electrons as totally free. We now introduce a periodic potential V(r). The underlying translational periodicity of the lattice is defined by the primitive lattice translation vectors T = n 1a 1 +n

In other words, ( ) is pseudo-periodic in the -space. Accordingly, the Topic 9-1: Bloch Theorem and the Central Equation Kittel Pages: 167-174 Summary: We begin here by postulating Bloch’s theorems which develop the form of the wavefunction in a periodic solid. We then show that the second postulate of Bloch’s theorem can be derived from the first. As we continue to prove Bloch’s first theorem we also derive the The Bloch theorem plays a central role in conduction electron dynamics. The theorem is derived and discussed in this chapter.
