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…
The non-vanishing effect of detuning errors in dynamical decoupling based quantum sensing experiments
J. E. Lang, T. Madhavan, J. -P. Tetienne +6
Characteristic dips appear in the coherence traces of a probe qubit when dynamical decoupling (DD) is applied in synchrony with the precession of target nuclear spins, forming the…
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…
Evidence for Primal sp2 Defects at the Diamond Surface: Candidates for Electron Trapping and Noise Sources
Alastair Stacey, Nikolai Dontschuk, Jyh-Pin Chou +11
Diamond materials are central to an increasing range of advanced technological demonstrations, from high power electronics, to nano-scale quantum bio-imaging with unprecedented sen…
