Exciton self-trapping in twisted hexagonal boron nitride homostructures
Sébastien Roux, Christophe Arnold, Etienne Carré +17
One of the main interests of 2D materials is their ability to be assembled with many degrees of freedom for tuning and manipulating excitonic properties. There is a need to underst…
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…
From the synthesis of hBN crystals to their use as nanosheets for optoelectronic devices
Camille Maestre, Yangdi Li, Vincent Garnier +11
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 sta…
Position-controlled quantum emitters with reproducible emission wavelength in hexagonal boron nitride
Clarisse Fournier, Alexandre Plaud, Sébastien Roux +9
Single photon emitters (SPEs) in low-dimensional layered materials have recently gained a large interest owing to the auspicious perspectives of integration and extreme miniaturiza…
Excellent electronic transport in heterostructures of graphene and monoisotopic boron-nitride grown at atmospheric pressure
J. Sonntag, J. Li, A. Plaud +4
Hexagonal boron nitride (BN), one of the very few layered insulators, plays a crucial role in 2D materials research. In particular, BN grown with a high pressure technique has prov…
Exciton-exciton annihilation in hBN
Alexandre Plaud, Léonard Schué, Kenji Watanabe +3
Known as a prominent recombination path at high excitation densities, exciton-exciton annihilation (EEA) is evidenced in bulk hexagonal boron nitride (hBN) by cathodoluminescence a…
Bright luminescence from indirect and strongly bound excitons in hBN
Leonard Schue, Lorenzo Sponza, Alexandre Plaud +6
A quantitative analysis of the excitonic luminescence efficiency in hexagonal boron nitride (hBN) is carried out by cathodoluminescence in the ultraviolet range and compared with z…
Single step synthesis and organization of gold colloids assisted by copolymer templates
Aurelien Sarrazin, Arthur Gontier, Alexandre Plaud +6
We report here an original single-step process for synthesis and self-organization of gold colloids by simply incorporating gold salts into a solution prepared with Polystyrene (PS…
Copolymer template control of gold nanoparticle synthesis via thermal annealing
A. Plaud, A. Sarrazin, J. Béal +6
We present here an original process combining top-down and bottom-up approaches by annealing a thin gold film evaporated onto a hole template made by etching a PS-PMMA copolymer fi…
