Room-temperature valence transition in a strain-tuned perovskite oxide

open access: yesNature Communications, 2022
Cobalt oxides have long been understood to display intriguing phenomena known as spin-state crossovers, where the cobalt ion spin changes vs. temperature, pressure, etc.

Metal-insulator transition in Mott-insulator FePS3

open access: yesAIP Advances, 2018
We have prepared single crystal of layered Mott-insulator FePS3 and investigated the pressure dependence of the electrical resistivity. FePS3 shows a metal-insulator transition between 10 and 11 GPa.

Electronic Coupling of Metal‐to‐Insulator Transitions in Nickelate‐Based Heterostructures

open access: yesAdvanced Electronic Materials, 2023
In rare earth nickelates, the metal‐to‐insulator transition observed as a function of temperature can be described using an electronic and a structural order parameter.

Metal-Insulator Transitions at Surfaces [PDF]

open access: yes, 2007
Various types of metal-insulator transitions are discussed to find conditions for which an ideal surface of a bulk insulator is metallic. It is argued that for the correlation-driven Mott metal-insulator transition the surface phase diagram should be expected to have the same topology as the phase diagram for magnetic order at surfaces: The ...

Deconfined metal-insulator transitions in quantum Hall bilayers

open access: yesPhysical Review Research, 2020
We propose that quantum Hall bilayers in the presence of a periodic potential at the scale of the magnetic length can host examples of a deconfined metal-insulator transition (DMIT), where a Fermi-liquid (FL) metal with a generic electronic Fermi surface

Critical Fidelity at the Metal-Insulator Transition [PDF]

open access: yesPhysical Review Letters, 2006
Using a Wigner Lorentzian random matrix ensemble, we study the fidelity, F(t), of systems at the Anderson metal-insulator transition, subject to small perturbations that preserve the criticality. We find that there are three decay regimes as perturbation strength increases: the first two are associated with a Gaussian and an exponential decay ...

A full gap above the Fermi level: the charge density wave of monolayer VS2

open access: yesNature Communications, 2021
A charge density wave (CDW) normally creates a gap at the Fermi level, inducing a metal-insulator transition. Here, the authors report that a CDW gap resides in the unoccupied states but induces a topological metal-metal transition at the Fermi level in ...

Metal-insulator-transition in SrTiO3 induced by argon bombardment combined with field effect

open access: yesAIP Advances, 2014
By fabricating the Field-Effect-Transistors on argon bombardment SrTiO3 substrates, not only we have achieved one of the best mobility for Field-Effect-Transistors fabricated on SrTiO3, but also realized strong field induced Metal-Insulator-Transition ...
