Single photon emission from droplet epitaxial quantum dots in the standard telecom window around a wavelength of 1.55 m
N. Ha, T. Mano, S. Dubos +3
We study the luminescence dynamics of telecom wavelength InAs quantum dots grown on InP(111)A by droplet epitaxy. The use of the ternary alloy InAlGaAs as a barrier material leads…
Current-injection quantum-entangled-pair emitter using droplet epitaxial quantum dots on GaAs(111)A
Neul Ha, Takaaki Mano, Takashi Kuroda +2
A source of single photons and quantum entangled photon pairs is a key element in quantum information networks. Here, we demonstrate the electrically driven generation of quantum e…
Magneto-spectroscopy of excited states in charge-tunable GaAs/AlGaAs [111] quantum dots
M. V. Durnev, M. Vidal, L. Bouet +11
We present a combined experimental and theoretical study of highly charged and excited electron-hole complexes in strain-free (111) GaAs/AlGaAs quantum dots grown by droplet epitax…
Size dependent line broadening in the emission spectra of single GaAs quantum dots: Impact of surface charges on spectral diffusion
N. Ha, T. Mano, Y. L. Chou +8
Making use of droplet epitaxy, we systematically controlled the height of self-assembled GaAs quantum dots by more than one order of magnitude. The photoluminescence spectra of sin…
Charge tuning in [111] grown GaAs droplet quantum dots
L. Bouet, M. Vidal, T. Mano +10
We demonstrate charge tuning in strain free GaAs/AlGaAs quantum dots (QDs) grown by droplet epitaxy on a GaAs(111)A substrate. Application of a bias voltage allows the controlled c…
Vanishing fine structure splittings in telecom wavelength quantum dots grown on (111)A surfaces by droplet epitaxy
X. Liu, N. Ha, H. Nakajima +7
The emission cascade of a single quantum dot is a promising source of entangled photons. A prerequisite for this source is the use of a symmetric dot analogous to an atom in a vacu…
One-dimensional pattern of Au nanodots by ion-beam-sputtering: formation and mechanism
J-H Kim, N-B Ha, J-S Kim +3
Highly ordered one-dimensional arrays of nanodots, or nanobeads, are fabricated by forming nanoripples and nanodots in sequence, entirely by ion-beamsputtering (IBS) of Au(001). Th…
