semiconductor-metal transition

https://doi.org/10.1351/goldbook.S05597
Any transition from a @S05591@ to a metallic state under the influence of a temperature or pressure change or both. Examples:
  1. Ti2O3: band-edge crossing in a @S05591@ to semimetal transition.
  2. SmS: localized level crossing a band edge. In SmS hydrostatic pressure above the @C01397@ \(P_{\text{c}}\approx 0.65\ \mathrm{GPa}\) broadens the Sm-5d band to make the band edge cross the Sm-\(4\text{f}^{6}\) level.
  3. A @L03608@.
  4. A @S06205@.
