Distinguishing different stackings in layered materials via luminescence spectroscopy
Matteo Zanfrognini, Alexandre Plaud, Ingrid Stenger +10
Despite its simple crystal structure, layered boron nitride features a surprisingly complex variety of phonon-assisted luminescence peaks. We present a combined experimental and th…
Colloidal Synthesis of Nanoparticles: from Bimetallic to High Entropy Alloys
Cora Moreira da Silva, Hakim Amara, Frédéric Fossard +3
At the nanometric scale, the synthesis of a random alloy (i.e. without phase segregation, whatever the composition) by chemical synthesis remains a not easy task, even for simple b…
Ultrasonication-Induced Extraction of Inner Shells from Double-Wall Carbon Nanotubes Characterized via In Situ Spectroscopy after Density Gradient Ultracentrifugation
Maksiem Erkens, Sofie Cambré, Emmanuel Flahaut +3
Even though ultrasonication is considered to be an effective method to disperse carbon nanotubes (CNTs), its devastating effects on the nanotubes are often neglected. Here, even mi…
Highly Polarized Light Emission from 6T@BNNT Nanohybrids
A. Badon, C. Allard, F. Fossard +6
The polarized fluorescence emission of organic fluorophores has been extensively studied in photonics and is increasingly exploited in single molecule scale bio-imaging. Expanding…
Highly Ordered Boron Nitride/Epigraphene Epitaxial Films on Silicon Carbide by Lateral Epitaxial Deposition
James Gigliotti, Xin Li, Suresh Sundaram +14
Realizing high-performance nanoelectronics requires control of materials at the nanoscale. Methods to produce high quality epitaxial graphene (EG) nanostructures on silicon carbide…
Assessing the reliability of the Raman peak counting method for the characterization of SWCNT diameter distributions: a cross-characterization with TEM
Alice Castan, Salomé Forel, Frédéric Fossard +6
Resonant Raman spectroscopy is a widely used technique for single-walled carbon nanotube (SWCNT) characterization, in particular in the radial breathing mode (RBM) range which prov…
A deep learning approach for determining the chiral indices of carbon nanotubes from high-resolution transmission electron microscopy images
G. D. Förster, A. Castan, A. Loiseau +5
Chiral indices determine important properties of carbon nanotubes (CNTs). Unfortunately, their determination from high-resolution transmission electron microscopy (HRTEM) images, t…
Tuning bimetallic catalysts for a selective growth of SWCNTs
Salomé Forel, Alice Castan, Hakim Amara +8
Recent advances in structural control during the synthesis of SWCNTs have in common the use of bimetallic nanoparticles as catalysts, despite the fact that their exact role is not…
Structural Properties of Double-Walled Carbon Nanotubes driven by Mechanical Interlayer Coupling
Ahmed Ghedjatti, Yann Magnin, Frédéric Fossard +5
Structural identification of double-walled carbon nanotubes (DWNT) is presented through a robust procedure based on the latest generation of transmission electron microscope, makin…
Angular resolved electron energy loss spectroscopy in hexagonal boron nitride
Frédéric Fossard, Lorenzo Sponza, Léonard Schué +4
Electron energy loss spectra have been measured on hexagonal boron nitride single crystals employing a novel electron energy loss spectroscopic set-up composed by an electron micro…
Characterization methods dedicated to nanometer-thick hBN layers
Leonard Schue, Ingrid Stenger, Frederic Fossard +2
Hexagonal boron nitride (hBN) regains interest as a strategic component in graphene engineering and in van der Waals heterostructures built with two dimensional materials. It is cr…
Exfoliating pristine black phosphorus down to the monolayer: photo-oxidation and electronic confinement effects
A. Favron, E. Gaufrès, F. Fossard +7
Thin layers of black phosphorus have recently raised interest for their two-dimensional (2D) semiconducting properties, such as tunable direct bandgap and high carrier mobilities.…
