Elements of Band Theoryntial the electronic energies form bands of allowed energy values separated by bands of forbidden energy values. Bloch functions were introduced as a consequence of the translational symmetry of the lattice. Energy bands obtained by a simplest tight-binding method and nearly free electron model are

Use of Elementary Group Theory in Calculating Band Structurery. We have shown that how group theory ideas can be used in obtaining the band structure of a solid. Group representations and characters of twodimensional square lattice are discussed in depth and empty lattice bands of the square lattice are illustrated. Concepts of irreducible representations an

Dielectric Properties of Solidslectricity and magnetism, and introduced concept of local field inside a solid. Then dispersion relations of self-sustaining collective modes and reflectivity of a solid are studied for various situations. Finally, the collective modes localized near the surface of a solid are also described and dis

Magnetism in Solidse of an atomor ion with an incomplete shell is determinedby Hund’s rules: The ground state has the maximum . consistent with the Pauli exclusion principle. It has the maximum . consistent with the maximum spin multiplicity 2. + 1 of Rule 1. The .-value is given by . ? . when a shell is less than hal
