Cathodoluminescence Study of a Quantum Dot in a Nanowire for Single-Photon Emission
Francis Granger, Fabrice Donatini, Edith Bellet-Amalric +4
Cathodoluminescence in a scanning electron microscope was applied to a semiconductor quantum dot in a nanowire able to emit single photons. We show that cathodoluminescence can be…

Calibration-free measurement of the phonon temperature around a single emitter
Francis Granger, Edith Bellet-Amalric, Kuntheak Kheng +3
The emission properties of a localized solid-state emitter are strongly influenced by its environment. The coupling to acoustic phonons impacts the coherence of the emitter and its…

Brightness and purity of a room-temperature single-photon source in the blue-green range
Francis Granger, Saransh Raj Gosain, Gilles Nogues +4
Single-photon sources are crucial for developing secure telecommunications. However, most systems operate at cryogenic temperatures. Here, we discuss a promising solid-state system…
