Amorphization-Depth-Dependent Bismuth Redistribution and Activation in Silicon for Quantum Devices
Youcef A. Bioud, Simon-Jean Michel, Sebastien Francoeur +2
Near-surface bismuth donors are promising for silicon quantum devices because of their rich electron-nuclear spin structure and long spin coherence, but their electrical activation…
Second-Order Raman Scattering in Exfoliated Black Phosphorus
Alexandre Favron, Félix Antoine Goudreault, Vincent Gosselin +7
Second-order Raman scattering has been extensively studied in carbon-based nanomaterials, \emph{e.g.} nanotube and graphene, because it activates normally forbidden Raman modes tha…
Probing Hyperbolic and Surface Phonon-Polaritons in 2D materials using Raman Spectroscopy
A. Bergeron, C. Gradziel, R. Leonelli +1
The hyperbolic dispersion relation of phonon-polaritons (PhPol) provides high-momentum states, highly directional propagation, subdiffractional confinement, large optical density o…
Visible Out-of-plane Polarized Luminescence and Electronic Resonance from Black Phosphorus
L. Schué, F. A. Goudreault, A. Righi +7
Black Phosphorus (BP) is unique among layered materials owing to its homonuclear lattice and strong structural anisotropy. While recent investigations on few layers BP have extensi…
Disentangling Phonon Channels in Nanoscale Thermal Transport
Samik Mukherjee, Marcin Wajs, Maria de la Mata +5
Phonon surface scattering has been at the core of heat transport engineering in nanoscale structures and devices. Herein, we demonstrate that this phonon pathway can be the sole me…
Mid-infrared polarized emission from black phosphorus light-emitting diodes
Junjia Wang, Adrien Rousseau, Mei Yang +3
The mid-infrared (MIR) spectral range is of immense use for civilian and military applications. The large number of vibrational absorption bands in this range can be used for gas s…
Spectral responsivity and photoconductive gain in thin film black phosphorus photodetectors
Junjia Wang, Adrien Rousseau, Elad Eizner +4
We have fabricated black phosphorus photodetectors and characterized their full spectral responsivity. These devices, which are effectively in the bulk thin film limit, show broadb…
Oxidation dynamics of ultrathin GaSe probed through Raman spectroscopy
Alaric Bergeron, John Ibrahim, Richard Leonelli +1
Gallium selenide (GaSe) is a 2D material with a thickness-dependent gap, strong non-linear optical coefficients and uncommon interband optical selection rules, making it interestin…
Taking advantage of light- and heavy-hole trions for optical spin initialization, control and readout
G. Éthier-Majcher, P. St-Jean, S. Francoeur
Optical control strategies in semiconductor nanostructures have almost exclusively relied on heavy-hole exciton and trion states. In the first part of this letter, we show that lig…
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.…
