説明
<jats:p> The transition metal chalcogenide Ni(S,Se) <jats:sub>2</jats:sub> is one of the few highly correlated, Mott-Hubbard systems without a strong first-order structural distortion that normally cuts off the critical behavior at the metal-insulator transition. The zero-temperature ( <jats:italic>T</jats:italic> ) transition was tuned with pressure, and significant deviations were found near the quantum critical point from the usual <jats:italic> T <jats:sup>1/2</jats:sup> </jats:italic> behavior of the conductivity characteristic of electron-electron interactions in the presence of disorder. The transport data for pressure and temperature below 1 kelvin could be collapsed onto a universal scaling curve. </jats:p>
