Journal ArticleDOI
Ultraviolet Photodetector Based on GaN/AlN Quantum Disks in a Single Nanowire
Lorenzo Rigutti,Maria Tchernycheva,A. De Luna Bugallo,Gwénolé Jacopin,François H. Julien,Luiz Fernando Zagonel,Katia March,Odile Stéphan,Mathieu Kociak,R. Songmuang +9 more
TL;DR: It is shown that the insertion of an axial heterostructure drastically reduces the dark current with respect to the binary nanowires and enhances the photosensitivity factor up to 5 x 10(2) for an incoming light intensity of 5 mW/cm(2).
Journal ArticleDOI
Nanometer Scale Spectral Imaging of Quantum Emitters in Nanowires and Its Correlation to Their Atomically Resolved Structure
Luiz Fernando Zagonel,Stefano Mazzucco,Marcel Tencé,Katia March,Romain Bernard,Benoît Laslier,Gwénolé Jacopin,Maria Tchernycheva,L. Rigutti,F. H. Julien,R. Songmuang,Mathieu Kociak +11 more
TL;DR: The present work opens the way both to fundamental studies of quantum confinement in closely packed quantum emitters and to characterizations of optoelectronic devices presenting carrier localization on the nanometer scale.

Nanometer Scale Spectral Imaging of Quantum Emitters in Nanowires and Its Correlation to Their Atomically Resolved Structure
Luiz Fernando Zagonel,Stefano Mazzucco,Marcel Tencé,Katia March,Romain Bernard,Benoît Laslier,Gwénolé Jacopin,Maria Tchernycheva,L. Rigutti,F. H. Julien,R. Songmuang,Mathieu Kociak +11 more
TL;DR: In this paper, the spectral imaging in the UV to visible range with nanometer scale resolution of closely packed GaN/AlN quantum disks in individual nanowires using an improved custom-made cathodoluminescence system is presented.
Journal ArticleDOI
Damage-free Vibrational Spectroscopy of Biological Materials in the Electron Microscope
Peter Rez,Toshihiro Aoki,Katia March,Dvir Gur,Ondrej L. Krivanek,Niklas Dellby,Tracy C. Lovejoy,Sharon G. Wolf,Hagai Cohen +8 more
TL;DR: The potential of aloof spectroscopy is demonstrated, which opens up the possibility of non-damaging compositional analyses of organic functional groups, including non-crystalline biological materials, at a spatial resolution of ∼10 nm, simultaneously combined with imaging in the electron microscope.
Journal ArticleDOI
Controlled Living Nanowire Growth: Precise Control over the Morphology and Optical Properties of AgAuAg Bimetallic Nanowires
Martin Mayer,Leonardo Scarabelli,Katia March,Thomas Altantzis,Moritz Tebbe,Mathieu Kociak,Sara Bals,F. Javier García de Abajo,Andreas Fery,Luis M. Liz-Marzán +9 more
TL;DR: This work is able to produce silver–gold–silver nanowires with a precise control over their total length and plasmonic properties by establishing a constant silver deposition rate on the tips of penta-twinned gold nanorods used as seed cores, clearly demonstrating that the presence of the gold core plays a marginal role, except for relatively short wires or high-energy modes.
