Quantum Theory Of Solids | Kittel Pdf

The nearly free electron model is a more advanced model for understanding the electronic structure of solids. Kittel presents a detailed analysis of this model, which assumes that the electrons in a solid can be treated as nearly free particles with weak periodic perturbations. The nearly free electron model provides a powerful framework for understanding the behavior of electrons in metals, enabling the calculation of important properties such as the Fermi surface and the electronic specific heat.

The Bloch theorem, introduced by Felix Bloch in 1928, is a fundamental concept in the quantum theory of solids. The theorem states that the wave function of an electron in a periodic potential can be written as a product of a plane wave and a periodic function with the same periodicity as the lattice. Kittel presents a detailed derivation of the Bloch theorem, highlighting its significance for understanding the behavior of electrons in solids. The Bloch theorem provides a powerful tool for analyzing the electronic structure of solids, enabling the classification of solids into metals, semiconductors, and insulators. The nearly free electron model is a more
