Leakage radiation microscopy of surface plasmons launched by a nanodiamond-based tip
O. Mollet, A. Cuche, A. Drezet +1
Leakage-radiation microscopy of a thin gold film demonstrates the ability of an ensemble of fluorescent diamond nanoparticles attached onto the apex of an optical tip to serve as a…
On the imaging of electron transport in semiconductor quantum structures by scanning-gate microscopy: successes and limitations
Hermann Sellier, Benoit Hackens, Marco Pala +6
This paper presents a brief review of scanning-gate microscopy applied to the imaging of electron transport in buried semiconductor quantum structures. After an introduction to the…
Coupling of excitons and defect states in boron-nitride nanostructures
C. Attaccalite, M. Bockstedte, A. Marini +2
The signature of defects in the optical spectra of hexagonal boron nitride (BN) is investigated using many body perturbation theory. A single BN-sheet serves as a model for differe…
Artificial Kagome Arrays of Nanomagnets: A Frozen Dipolar Spin Ice
N. Rougemaille, F. Montaigne, B. Canals +8
Magnetic frustration effects in artificial kagome arrays of nanomagnets are investigated using x-ray photoemission electron microscopy and Monte Carlo simulations. Spin configurati…
Hysteresis loops of the magnetoconductance in graphene devices
A. Candini, C. Alvino, W. Wernsdorfer +1
We report very low temperature magnetoconductance DeltaG measurements on graphene devices with the magnetic field H applied parallel to the carbon sheet. The DeltaG(H) signal depen…
