In the wide world of 2D materials, hexagonal boron nitride (hBN) holds a special place due to its excellent characteristics. In addition to its thermal, chemical and mechanical stability, hBN demonstrates high thermal conductivity, low compressibilit

Colloidal Synthesis of Nanoparticles: from Bimetallic to High Entropy Alloys
Autor: Cora Moreira Da Silva, Hakim Amara, Fédéric Fossard, Armelle Girard, Annick Loiseau, Vincent Huc
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 binary type systems. In this context, a unique approach based on the co

Flash laser annealing for controlling size and shape of magnetic alloy nanoparticles
Autor: Damien Alloyeau, Christian Ricolleau, Cyril Langlois, Yann Le Bouar, Annick Loiseau
Publikováno v: Beilstein Journal of Nanotechnology, Vol 1, Iss 1, Pp 55-59 (2010)
We propose an original route to prepare magnetic alloy nanoparticles with uniform size and shape by using nanosecond annealing under pulsed laser irradiation. As demonstrated here on CoPt nanoparticles, flash laser annealing gives an unprecedented op

2D boron nitride (2D-BN) was synthesized by gas-source molecular beam epitaxy on polycrystalline and monocrystalline Ni substrates using gaseous borazine and active nitrogen generated by a remote plasma source. The excess of nitrogen atoms allows to

International audience; Using a new time-resolved cathodoluminescence system dedicated to the UV spectral range, we present a first estimate of the radiative lifetime of free excitons in hBN at room temperature. This is carried out from a single expe

2D Materials, 2021, 8 (2), pp.021001. ⟨10.1088/2053-1583/abca81⟩
Atomic layers of Black Phosphorus (BP) present unique opto-electronic properties dominated by a direct tunable bandgap in a wide spectral range from visible to mid-infrared. In this work, we investigate the infrared photoluminescence of BP single cry
