The team harnessed diamond chemical vapour deposition capabilities available at ANFF VIC’s flagship facility, the Melbourne Centre for Nanofabrication, that are capable of introducing boron while diamond is being grown. “The investment by ANFF in a state-of-the-art facility for the growing of high quality, ultra-pure, single crystal diamond films – and in particular the investment in a high purity boron doping line into the reactor – is a big part of what made this research possible,” Alastair said. The team demonstrated that adding a dose of boron – a process called doping – causes diamond to show superconducting properties at temperatures around 2K. The team’s boron-doped diamond will now be used as the base material for a range of new sensors including SQUIDS (for magnetic field sensing) and single photon detectors, as well as in integrated diamond quantum photonic devices.
