Any transition from a @[email protected] to a metallic state under the influence of a temperature or pressure change or both. Examples:
- Ti2O3: band-edge crossing in a @[email protected] to semimetal transition.
- SmS: localized level crossing a band edge. In SmS hydrostatic pressure above the @[email protected] \(P_{\text{c}}\approx 0.65\ \mathrm{GPa}\) broadens the Sm-5d band to make the band edge cross the Sm-\(4\text{f}^{6}\) level.
