... electrons can be lost by thermal excitation leaving behind an unsaturated bond or hole. In the silicon doped by an element in group 15 of the periodic table (e.g. phosphorus, arsenic, or antimony), some silicon atoms in the lattice are substituted by the dopant atoms as shown in Fig. 2(b). Because t ...

... X-rays are short wavelength photons (0.1Å to 10Å), usually produced when high-energy electrons interact with solid matter. The electrons lose energy by collisions with the atoms and much of the lost energy is radiated as photons. (The rest of the energy is dissipated as heat in the solid material, s ...

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.
