Elemental boron becomes a superconductor at extreme pressures around 160 gigapascals (GPa). Its superconducting critical temperature increases with pressure, reaching 11.2 kelvin (K) at 250 GPa.

Area of Science:

  • Condensed matter physics
  • Materials science
  • High-pressure physics

Background:

  • Light element metals are predicted to display unique electronic ordering.
  • Boron-containing materials are of significant interest due to their high superconducting transition temperatures.

Purpose of the Study:

  • To investigate the high-pressure behavior of elemental boron.
  • To determine the pressure-induced metallization and superconductivity in boron.

Main Methods:

  • Electrical conductivity measurements were performed on elemental boron.
  • Diamond anvil cell techniques were used to achieve ultra-high pressures.

Main Results:

  • Boron transitions from a nonmetal to a superconductor at approximately 160 gigapascals (GPa).

  • The superconducting critical temperature (Tc) was observed to increase from 6 kelvin (K) at 175 GPa to 11.2 K at 250 GPa.
  • A positive pressure derivative of superconductivity (0.05 K/GPa) was determined.

    • Conclusions:

    • The metallization pressure aligns with theoretical predictions, but superconductivity in boron requires further theoretical exploration.
    • This study sets new records for electrical conductivity and superconductivity investigations at extreme pressures.
