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…
Apparent delocalisation of the current flow in metallic wires observed with diamond nitrogen-vacancy magnetometry
J. -P. Tetienne, N. Dontschuk, D. A. Broadway +5
We report on a quantitative analysis of the magnetic field generated by a continuous current running in metallic micro-wires fabricated on an electrically insulating diamond substr…
Spatial mapping of band bending in semiconductor devices using in-situ quantum sensors
D. A. Broadway, N. Dontschuk, A. Tsai +8
Band bending is a central concept in solid-state physics that arises from local variations in charge distribution especially near semiconductor interfaces and surfaces. Its precisi…
Magnetic noise from ultra-thin abrasively deposited materials on diamond
S. E. Lillie, D. A. Broadway, N. Dontschuk +6
Sensing techniques based on the negatively charged nitrogen-vacancy (NV) centre in diamond have emerged as promising candidates to characterise ultra-thin and 2D materials. An outs…
Proximity-induced artefacts in magnetic imaging with nitrogen-vacancy ensembles in diamond
J. -P. Tetienne, D. A. Broadway, S. E. Lillie +6
Magnetic imaging with ensembles of nitrogen-vacancy (NV) centres in diamond is a recently developed technique that allows for quantitative vector field mapping. Here we uncover a s…
