Persistence and emergence of quantum defects through pressure-induced phase changes
Alexander J Healey, Alan Salek, Christopher T-K Lew +15
Extreme pressures can transform materials and their properties, but probing these in-situ is made challenging by the small sample volumes and access requirements demanded by diamon…
Nitrogen-vacancy centre formation via local femto-second laser annealing of diamond
Davin Yue Ming Peng, Alexander J Healey, Rebecca Griffin +7
Emerging quantum technologies based on the nitrogen-vacancy (NV) centre in diamond require carefully engineered material with controlled defect density, optimised NV formation proc…
The color center: a ubiquitous visible and near-infrared-II quantum emitter in nitrogen-doped diamond
Brett C. Johnson, Mitchell O. de Vries, Alexander J. Healey +13
Photoluminescent defects in diamond, like the nitrogen-vacancy (NV) color center, are at the forefront of emerging optical quantum technologies. Most emit in the visible and near-i…
Imaging magnetic switching in orthogonally twisted stacks of a van der Waals antiferromagnet
Alexander J Healey, Cheng Tan, Boris Gross +9
Stacking van der Waals magnets holds promise for creating new hybrid materials with properties that do not exist in bulk materials. Here we investigate orthogonally twisted stacks…
Radiofrequency receiver based on isotropic solid-state spins
Islay O. Robertson, Brett C. Johnson, Giannis Thalassinos +5
Optically addressable solid-state spins have been proposed as robust radiofrequency (RF)-optical transducers sensitive to a specific RF frequency tuned by an external static magnet…
3D-mapping and manipulation of photocurrent in an optoelectronic diamond device
A. A. Wood, D. J. McCloskey, N. Dontschuk +10
Characterising charge transport in a material is central to the understanding of its electrical properties, and can usually only be inferred from bulk measurements of derived quant…
Imaging current paths in silicon photovoltaic devices with a quantum diamond microscope
S. C. Scholten, G. J. Abrahams, B. C. Johnson +11
Magnetic imaging with nitrogen-vacancy centers in diamond, also known as quantum diamond microscopy, has emerged as a useful technique for the spatial mapping of charge currents in…
Creation of nitrogen-vacancy centers in chemical vapor deposition diamond for sensing applications
T. Luo, L. Lindner, J. Langer +12
The nitrogen-vacancy (NV) center in diamond is a promising quantum system for magnetometry applications exhibiting optical readout of minute energy shifts in its spin sub-levels. K…
Comparison of different methods of nitrogen-vacancy layer formation in diamond for widefield quantum microscopy
A. J. Healey, A. Stacey, B. C. Johnson +5
Thin layers of near-surface nitrogen-vacancy (NV) defects in diamond substrates are the workhorse of NV-based widefield magnetic microscopy, which has applications in physics, geol…
Microscopic imaging of elastic deformation in diamond via in-situ stress tensor sensors
D. A. Broadway, B. C. Johnson, M. S. J. Barson +12
The precise measurement of mechanical stress at the nanoscale is of fundamental and technological importance. In principle, all six independent variables of the stress tensor, whic…
