Nanoelectronics Using Metal–Insulator Transition
Advanced Materials, 2023AbstractMetal–insulator transition (MIT) coupled with an ultrafast, significant, and reversible resistive change in Mott insulators has attracted tremendous interest for investigation into next‐generation electronic and optoelectronic devices, as well as a fundamental understanding of condensed matter systems.

Research on metal–insulator transitions is at the moment quite fashionable. In many materials the electrical behavior changes from metallic to nonmetallic when the pressure, temperature or magnetic field is varied or (as in alloys) when the composition is varied, and the theoretical description of these processes is quite complicated.

Localization, Interactions, and the Metal-Insulator Transition
Science, 1984Recent advances in our understanding of electronic conduction have pointed up deficiencies in traditional thinking. For a metal at a sufficiently low temperature, it is known both theoretically and experimentally that the conventional picture in terms of the Boltzmann theory breaks down.

Metal-insulator transition in the Hubbard model
Physica B: Condensed Matter, 1999Abstract The scaling behaviour of the dynamical properties near the metal–insulator transition in the infinite-dimensional Hubbard model is studied via Wilson's numerical renormalization group method, after using the standard mapping into an effective Anderson impurity model.

General theory of the metal-insulator transition
Physical Review B, 1992We present a general theory of the metal-insulator transition based on the formal introduction of an auxiliary irrotational gauge field and the subsequent behavior of the system in response to it. Correspondingly general scaling relations are derived which determine the point of transition at a critical value of the controlling density in terms of a ...

In the first section we specify an insulator as a substance with a vanishing electrical conductivity in a (weak) static electrical field at zero temperature. The transport of electrical charge in the solid state is provided by electrons that are subjected to the Coulomb interaction with the ions and the other electrons.

METAL-INSULATOR TRANSITION IN THE HUBBARD MODEL
Modern Physics Letters B, 1996We study the metal-insulator transition of the d-dimensional Hubbard model by treating the hopping term between adjacent 1-d chains in the frame of a Clifford linearization scheme, and keeping the full model along the chains. A general equation for the critical point is worked out in terms of the correlation functions of the one-dimensional model ...

In one, two and now three dimensions, the behavior of amorphous materials is challenging the traditional concepts of metals and insulators. Over a year ago experiments showed that one- and two-dimensional disordered materials appear to move continuously rather than abruptly from insulating to metal-like phases as their randomness decreases. Even in the

In analyzing various phenomena in TM compounds in the previous chapter, we have already several times come across the situation when a material, depending on conditions, can be in an insulating or in a metallic state. Such metal–insulator transitions can be caused either by doping (a change in band filling) or by temperature, pressure, magnetic field ...
