Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …

A generalization of the local density approximation (LDA) method for systems with strong
Coulomb correlations is described which gives a correct description of the Mott insulators …

We present a comprehensive series of electrical transport (conductivity, magnetoresistance,
and Hall effect), thermodynamic (specific heat, magnetic susceptibility, and magnetization) …

We review many-body effects, their microscopic origin, as well as their impact on
thermoelectricity in correlated narrow-gap semiconductors. Members of this class—such as …

The thermal expansion and heat capacity of Fe Sb 2 at ambient pressure agrees with a
picture of a temperature induced spin state transition within the Fe t 2 g multiplet. However …

The intermetallic FeSi exhibits an unusual temperature dependence in its electronic and
magnetic degrees of freedom, epitomized by the cross-over from a low-temperature …

Semiconducting substances form one of the most important families of functional materials.
However, semiconductors containing only metals are very rare. The chemical mechanisms …

From an investigation of the optical conductivity of FeSi single crystals using Fourier-
transform infrared spectroscopy in the frequency range from 30 to 20 000 cm− 1 we …

Materials where electrons show nearly localized rather than itinerant behaviour, such as the
high-temperature superconducting copper oxides, or manganate oxides, are attracting …

Monosilicides of transition metals crystallizing in a B20 (FeSi-type) structure (space group
P2 1 3,# 198) possess a wide range of specific properties. Among them are semiconductors …
