Subsequently, the Einstein model, based on a single phonon frequency, was extended by Peter Debye by including the complete phonon

Thomas Jäger,Alexander Höse,Kai Oppermanny forbidden energy gaps. The approximations with bound electrons (F. Bloch) and with nearly-free electrons (R. Peierls) are discussed. Depending on how the energy states within the bands are occupied by electrons, we deal with electrical conductors, semiconductors, or insulators.

Kathrin Brockmann,Eva Strickmannn 1911 he discovered superconductivity, where electric current flows without detectable resistance. Superconductivity requires that distinct critical values of the temperature and magnetic field are not exceeded. Eventually it was found that a magnetic field is expelled from the interior of a superc

In an external magnetic field the magnetization of a paramagnet is described classically by the Langevin function, to be replaced by the Brillouin function in the case of quantization effects. In a ferromagnet the elementary magnets are spontaneously oriented along a distinct direction. T
