Solid-State Physics 15 Min Read The Physics of Solid-State Electronics: Band Theory & P-N Junction Mechanics Transitioning from single-atom quantum models to continuous electronic energy states in a crystalline lattice. To understand modern semiconductor technology at a university level, we must move past classical Bohr "planetary" atomic models. Instead, we look at the quantum behavior of electrons under the influence of periodic electrostatic potentials. 1. Band Theory and the Kronig-Penney Potential In a single, isolated atom, electrons occupy discrete, narrow energy levels. However, when individual atoms assemble into a crystalline lattice, their outer atomic orbitals overlap. According to the Pauli Exclusion Principle , no two identical fermions can occupy the...
