Showing papers on "Mott transition published in 1973"
TL;DR: In this article, a semiconductor-metal transition in the electrical resistance of NiS 2, which has been suggested to be a Mott transition, is observed with decreasing temperature under pressure up to 44 kbar.

TL;DR: In this article, the critical donor concentration for the Mott transition in many-valley semiconductors was calculated and it was shown that the model predicts values of over 45% larger than in single-valleys.
Abstract: We have calculated the critical donor concentration ${n}_{c}$ for the Mott transition in many-valley semiconductors. Our accurate numerical solution of the Schr\"odinger equation for Mott's model, as extended by Krieger and Nightingale, shows that previously reported good agreement with experiments has been in part the fortuitous result of calculational simplifications. We also find that the model predicts values of ${n}_{c}^{\frac{1}{3}}{a}_{H}$ (where ${a}_{H}$ is the effective Bohr radius in the material) over 45% larger in single-valley semiconductors than in Ge and Si (four and six valleys, respectively) and suggest such experiments as further meaningful tests of the model.

TL;DR: In this paper, a metal-nonmetal transition observed in sodium dispersed in argon is interpreted to be a Mott transition, based on a variational determination of bound states in a dielectrically screened pseudopotential.

TL;DR: In this article, the metal-non metal transition in doped silicon is studied by NMR and the result, together with the static susceptibility measurement and the theoretical interpretation with the Hubbard model, seems to give a sound basis for the Mott transition picture.

TL;DR: In this paper, the materials around the Mott transition lying in the linking region between the standard band and salt-like regimes are discussed, and some discussion is given of the materials in this region.

TL;DR: This chapter takes up transitions which change the electrical properties of metals or compounds by establishing a new ground state for the system by changes in physical rather than chemical properties.
Abstract: In this chapter we take up transitions which change the electrical properties of metals or compounds by establishing a new ground state for the system. Changes in physical rather than chemical properties are involved in these transitions, in contrast to the events discussed in later chapters.
