Homogeneous system: Band structure is an intrinsic property of a material, which assumes that the material is homogeneous. Practically, this means that the chemical makeup of the material must be uniform throughout the piece. Non-interactivity: The band structure describes "single electron states Zobacz więcej 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 Zobacz więcej Assumptions and limits of band structure theory Band theory is only an approximation to the quantum state of a solid, which applies to solids … Zobacz więcej 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.
