Imaging of Gate-Controlled Suppression of Superconductivity via the Meissner Effect
P. J. Scheidegger, K. J. Knapp, U. Ognjanovic +5
It was recently discovered that supercurrents flowing through thin superconducting nanowires can be quenched by a gate voltage. This gate control of supercurrents, known as the GCS…
Modeling temperature-dependent population dynamics in the excited state of the nitrogen-vacancy center in diamond
Stefan Ernst, Patrick J. Scheidegger, Simon Diesch +1
The nitrogen-vacancy (NV) center in diamond is well known in quantum metrology and quantum information for its favorable spin and optical properties, which span a wide temperature…
Temperature dependence of photoluminescence intensity and spin contrast in nitrogen-vacancy centers
Stefan Ernst, Patrick J. Scheidegger, Simon Diesch +2
We report on measurements of the photoluminescence (PL) properties of single nitrogen-vacancy (NV) centers in diamond at temperatures between 4-300 K. We observe a strong reduction…
Imaging of sub-A currents in bilayer graphene using a scanning diamond magnetometer
M. L. Palm, W. S. Huxter, P. Welter +9
Nanoscale electronic transport gives rise to a number of intriguing physical phenomena that are accompanied by distinct spatial patterns of current flow. Here, we report on sensiti…
