✦ Synopsis

We give a survey on our current understanding of electron-structure interrelations in disordered metals. The ability to decrease the electronic ground-state energy induces a peak in the static structure function close to 2k F over large composition ranges and a corresponding pseudo gap in the electronic density of states at the Fermi energy. The depth of the gap is directly related to the intensity of the peak at 2k F and shows influences on many physical properties. We report on the electron-structure relation itself, the Hall coefficient and the thermopower. Both the Hall coefficient and the thermopower show typical deviations of the free electron behaviour whenever a pseudo gap at E F exists.
