Hydrostatic Pressure

A universal quantum tunnelling parameter yet to be fully explored is Hydrostatic Pressure. The hope is to use diamond anvils to apply pressures greater than one Mbar. Efforts in the group will focus on:

  • Growth of large high-quality diamonds and encasing of microcircuitry by chemical vapour deposition (CVD)
  • Microfabrication, manipulation and bonding by focused ion beam (FIB) techniques
  • In situ pressure variation with high-homogeneity media
  • Development of a range of measurement techniques
  • Synthesis of new high-strength materials
