Imaging current flow and injection in scalable graphene devices through NV-magnetometry
Kaj Dockx, Michele Buscema, Saravana Kumar +7
The global electronic properties of solid-state devices are strongly affected by the microscopic spatial paths of charge carriers. Visualising these paths in novel devices produced…
Scattering contrast in GHz frequency ultrasound subsurface atomic force microscopy for detection of deeply buried features
Maarten H. van Es, Benoit A. J. Quesson, Abbas Mohtashami +4
While Atomic Force Microscopy is mostly used to investigate surface properties, people have almost since its invention sought to apply its high resolution capability to image also…
Angle-resolved polarimetry measurements of antenna-mediated fluorescence
Abbas Mohtashami, Clara I. Osorio, A. Femius Koenderink
Optical phase-array antennas can be used to control not only the angular distribution but also the polarization of fluorescence from quantum emitters. The emission pattern of the r…
Suitability of nanodiamond NV centers for spontaneous emission control experiments
Abbas Mohtashami, A. Femius Koenderink
NV centers in diamond are generally recognized as highly promising as indefinitely stable highly efficient single-photon sources. We report an experimental quantification of the br…
Nanomechanical method to gauge emission quantum yield applied to NV-centers in nanodiamond
Martin Frimmer, Abbas Mohtashami, A. Femius Koenderink
We present a technique to nanomechanically vary the distance between a fluorescent source and a mirror, thereby varying the local density of optical states at the source position.…
Non-resonant feeding of photonic crystal nanocavity modes by quantum dots
A. Laucht, N. Hauke, A. Neumann +9
We experimentally probe the non-resonant feeding of photons into the optical mode of a two dimensional photonic crystal nanocavity from the discrete emission from a quantum dot. Fo…
Temporal Monitoring of Non-resonant Feeding of Semiconductor Nanocavity Modes by Quantum Dot Multiexciton Transitions
A. Laucht, M. Kaniber, A. Mohtashami +3
We experimentally investigate the non-resonant feeding of photons into the optical mode of a zero dimensional nanocavity by quantum dot multiexciton transitions. Power dependent ph…
Phonon-assisted transitions from quantum dot excitons to cavity photons
Ulrich Hohenester, Arne Laucht, Michael Kaniber +4
For a single semiconductor quantum dot embedded in a microcavity, we theoretically and experimentally investigate phonon-assisted transitions between excitons and the cavity mode.…
