"In solid-state physics, the electronic band structure (or simply band structure) of a solid describes the range of energy levels that electrons may have within it, as well as the ranges of energy that they may not have (called band gaps or forbidden bands). Band theory derives these bands and band gaps by examining … Ver mais The electrons of a single, isolated atom occupy atomic orbitals each of which has a discrete energy level. When two or more atoms join together to form a molecule, their atomic orbitals overlap and hybridize. Similarly, if a large … Ver mais Assumptions and limits of band structure theory Band theory is only an approximation to the quantum state of a solid, which applies to solids consisting … Ver mais To understand how band structure changes relative to the Fermi level in real space, a band structure plot is often first simplified in the form of a band diagram.
