Quantum materials processed by non-equilibrium methods

 A. Research topics

  • Si/Ge-based superconducting circuits
  • Defect engineering in SiC for quantum spintronics
  • Nanostructures for single photon emitters and receivers
  • Chalcogen-hyperdoped nanowires for quantum sensors

B. Non-equilibrium methods

  • Thermal processing by millisecond flash lamp or nanosecond pulsed laser
  • Energetic particle irradiation using ions/electrons
  • Isotopically pure doping by ion implantation
