Ordered InAs quantum dots on pre-patterned GaAs (0 0 1) by local oxidation nanolithography
J. Martín-Sánchez, Y. González, L. González +5
Ordered InAs quantum dot (QD) arrays have been obtained on pre-patterned GaAs (0 0 1) substrates by atomic force microscopy (AFM) local oxidation nanolithography. Prior to InAs mol…
Contribution to the study of sub-bandgap photon absorption in quantum dot InAs/AlGaAs intermediate band solar cells
Juan Villa, Iñigo Ramiro, José María Ripalda +4
Intermediate band solar cells (IBSCs) pursue the increase in efficiency by absorbing below-bandgap energy photons while preserving the output voltage. Experimental IBSCs based on q…
Nano-patterned magnonic crystals based on ultrathin YIG films
M. Collet, M. Evelt, V. E. Demidov +9
We demonstrate a microscopic magnonic-crystal waveguide produced by nano-patterning of a 20 nm thick film of Yttrium Iron Garnet. By using the phase-resolved micro-focus Brillouin…
Gate Tunable Photovoltaic Effect in MoS2 vertical P-N Homostructures
Simon A. Svatek, Elisa Antolin, Der-Yuh Lin +8
P-n junctions based on vertically stacked single or few layer transition metal dichalcogenides (TMDCs) have attracted substantial scientific interest. Due to the propensity of TMDC…
Fluctuations of the Electromagnetic Local Density of States as a Probe for Structural Phase Switching
N. de Sousa, J. J. Sáenz, F. Scheffold +2
We study the statistics of the fluorescence decay rates for single quantum emitters embedded in a scattering medium undergoing a phase transition. Under certain circumstances, the…
Magnetic-field control of near-field radiative heat transfer and the realization of highly tunable hyperbolic thermal emitters
Edwin Moncada-Villa, Victor Fernandez-Hurtado, Francisco J. Garcia-Vidal +2
We present a comprehensive theoretical study of the magnetic field dependence of the near-field radiative heat transfer (NFRHT) between two parallel plates. We show that when the p…
Electronic control of the spin-wave damping in a magnetic insulator
A. Hamadeh, O. d Allivy Kelly, C. Hahn +12
It is demonstrated that the decay time of spin-wave modes existing in a magnetic insulator can be reduced or enhanced by injecting an in-plane dc current, , in an adja…
Probing quantum confinement within single core-multishell nanowires
Gema Martínez-Criado, Alejandro Homs, Benito Alén +6
Theoretically core-multishell nanowires under a cross-section of hexagonal geometry should exhibit peculiar confinement effects. Using a hard X-ray nanobeam, here we show experimen…
Bichromatic dressing of a quantum dot detected by a remote second quantum dot
M. Maragkou, C. Sánchez-Muñoz, S. Lazić +8
We demonstrate an information transfer mechanism between two dissimilar remote InAs/GaAs quantum dots weakly coupled to a common photonic crystal microcavity. Bichromatic excitatio…
Interplay between interferences and electron-electron interactions in epitaxial graphene
B. Jouault, B. Jabakhanji, N. Camara +3
We separate localization and interaction effects in epitaxial graphene devices grown on the C-face of a 4H-SiC substrate by analyzing the low temperature conductivities. Weak local…
Field enhancement in subnanometer metallic gaps
Antonio Garcia-Martin, Daniel R. Ward, Douglas Natelson +1
Motivated by recent experiments [Ward et al., Nature Nanotech. 5, 732 (2010)], we present here a theoretical analysis of the optical response of sharp gold electrodes separated by…
Magnetooptic enhancement and magnetic properties in Fe antidot films with hexagonal symmetry
E. Th. Papaioannou, V. Kapaklis, P. Patoka +5
The magnetooptic and magnetic properties of hexagonal arrays of holes in optically thin iron films are presented. We analyze their dependence on the hole radius and compare the res…
Optical pumping of charged excitons in unintentionally doped InAs quantum dots
G. Munoz-Matutano, B. Alen, J. Martinez-Pastor +3
As an alternative to commonly used electrical methods, we have investigated the optical pumping of charged exciton complexes addressing impurity related transitions with photons of…
Absorption and photoluminescence spectroscopy on a single self-assembled charge-tunable quantum dot
S. Seidl, M. Kroner, P. A. Dalgarno +8
We have performed detailed photoluminescence (PL) and absorption spectroscopy on the same single self-assembled quantum dot in a charge-tunable device. The transition from neutral…
