Ion Concentration and Voltage Imaging with Fluorescent Nanodiamonds
Patrick Voorhoeve, Hiroshi Abe, Takeshi Ohshima +5
The nitrogen-vacancy (NV) center in diamond exists in different charge states with distinct photoluminescence properties, which are sensitive to the nanoscale electrochemical envir…
Photoelectrical detection and characterization of divacancy and PL5-PL7 spins in silicon carbide
Naoya Morioka, Tetsuri Nishikawa, Hiroshi Abe +2
Photoelectrical detection of magnetic resonance (PDMR) offers a scalable alternative to optical readout of spin defects in semiconductors and is particularly promising for near-inf…
Photoionization current spectroscopy of individual silicon vacancies in silicon carbide
Kazuki Okajima, Tetsuri Nishikawa, Hiroshi Abe +5
Defect charge-state dynamics are central to both spin-photon interfaces and photoelectrical spin readout. Despite the significance of silicon vacancies (V1/V2) in silicon carbide (…
The properties of the nitrogen-vacancy center in milled chemical vapor deposition nanodiamonds
Alessandro Mameli, Giannis Thalassinos, Marco Capelli +14
Fluorescent nanodiamonds (FNDs) containing negatively charged nitrogen-vacancy (NV-) centers are vital for many emerging quantum sensing applications from magnetometry to intracell…
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…
