... When electrons are in the lowest energy state, they are said to be in the ground state. When a flame or other source of energy is absorbed by the electrons, they are promoted to a higher energy state (excited state). When an electron in an excited state returns to a lower energy state, it emits a ph ...

First of all, we see from (1.37) that NS ∝ V0 , i.e., for inifinite potential walls we also get infinitely many states, as is also reflected in Eq. (1.21). Furthermore, when V0 increases, the curves for λ in Fig. 1.3 b ...

Tight binding

In solid-state physics, the tight-binding model (or TB model) is an approach to the calculation of electronic band structure using an approximate set of wave functions based upon superposition of wave functions for isolated atoms located at each atomic site. The method is closely related to the LCAO method used in chemistry. Tight-binding models are applied to a wide variety of solids. The model gives good qualitative results in many cases and can be combined with other models that give better results where the tight-binding model fails. Though the tight-binding model is a one-electron model, the model also provides a basis for more advanced calculations like the calculation of surface states and application to various kinds of many-body problem and quasiparticle calculations.
