Birgit Blättel-Mink,Alexander Ebnerour. Indeed, calculations of many-body effects have only been performed for either a uniform electron gas or for metals having an almost spherical Fermi surface such as Na. Practically nothing is known at the present time about many-body effects in metals having a complicated electron structure.

Dietfried Globocnik,Søren Salomocts due to the linear and quadratic electro-optic effects. The latter is invoked to interpret an anomalous modulation most visible in diodes with their junction field in the direction. The origin of the higher optical dielectric constant in the junction, which is mainly responsible for mode confinement, is not as yet understood.

,Die Marktposition führender Länder,sent-day experiments which have been selected from the main fields of application namely (1) phonon scattering in crystals, (2) scattering on fluctuations in liquids, and (3) scattering on magnetic fluctuations. This means that we restrict ourselves on the investigation of collective phenomena by coherent scattering.

Energy Band Structure of Semiconductors,n the range from 0.5 to 5 eV; some were small band-gap semiconductors or semi-metals; the others were insulators with band gaps larger than 5 eV. All these materials are of scientific interest; many, especially Si, Ge, SiC, and various III–V, II–VI, and IV–VI compounds, are also of considerable technological interest.

Innovation: Grundlagen und Grundbegriffe, potential barrier without acquiring enough energy to pass over the top. If our discussion is limited to the macroscopic potential barriers in the bulk of solids rather than those on the surface or in the atomic or crystal field, tunneling barriers, which we are familiar with, are classified into tw
