Semiconductor electronics provides an excellent demonstration of the close connection between modern engineering and quantum physics. It was an understanding of the electronic structure of semiconductors in the 1940s that led to the invention of the first transistor (Bardeen and Brattain, 1948; Brattain and Bardeen, 1948; Shockley and Pearson, 1948 ...

Excited states of73Se have been investigated up to spin, 21/2 using techniques of in-beamγ-ray spectroscopy in connection with the70Ge(α, n) reaction. Mean lifetimes of 12 levels have been determined applying Doppler-shift andγ-RF-methods. Five different bands have been identified that reflect a variety of different excitation modes. The decoupled 9/2+

The property which distinguishes semiconductors from other materials concerns the behavior of their electrons, in particular the existence of gaps in their electronic excitation spectra. The microscopic behavior of electrons in a solid is most conveniently specified in terms of the electronic band structure.

The theoretical determination of the unoccupied electronic states is an important tool for understanding the results of experimental techniques such as X-ray absorption, inverse photoemission and bremsstrahlung isochromat spectroscopy. The availability of reliable calculations always serves as a starting point to interpret the measured spectra in the ...

Inherent to wave propagation in a periodic medium is the formation of band structure in the dispersion relation. As an example, when electrons with energy E and wavevector k propagate in a periodic lattice, electronic band structure E(k) results; this is one of the basic concepts of solid state physics.

The aim of this chapter is to present, in detail, some theoretical methods used to calculate electronic band structures in crystals. The solution of Schrodinger’s equation for an electron moving in a periodic potential meets insurmountable difficulties if one does not make a number of simplifications.

In deriving (4.24), we did not have to assume that V(r) was small, and in principle this set of equations enables us to find the energies e n (k) and the wave-functions ψ nk (r) for an electron moving in any periodic potential V(r) But in practice, the equations can be solved at all easily only if most of the coefficients V G are small (compared with ...

In recent years, the field of topological band theory has experienced a rapid and substantial growth. This sudden development reflects in the discovery of a plethora of new topological materials via an effective analysis performed within the framework of topological quantum chemistry formalism.
