Effect of extended defects on AlGaN QDs for electron-pumped UV-emitters
Jesus Cañas, Névine Rochat, Adeline Grenier +8
We study the origin of bimodal emission in AlGaN/AlN QD superlattices displaying high internal quantum efficiency (around 50%) in the 230-300 nm spectral range. The secondary emiss…
AlGaN/AlN Stranski-Krastanov quantum dots for highly efficient electron beam pumped emitters: The role of miniaturization and composition to attain far UV-C emission
Jesus Cañas, Anjali Harikumar, Stephen T. Purcell +6
Conventional ultraviolet (UV) lamps for disinfection emit radiation in the 255-270 nm range, which poses a high risk of causing cancer and cataracts. To address these concerns, sol…
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…
Quantitative analysis of the blue-green single-photon emission from a quantum dot in a thick tapered nanowire
Saransh Raj Gosain, Edith Bellet-Amalric, Eric Robin +5
Quantum dots acting as single photon emitters in the blue-green range are fabricated and characterized at cryogenic temperature. They consist in CdSe dots inserted in (Zn,Mg)Se nan…
Regulated dynamics with two-monolayer steps in vapor-solid-solid growth of nanowires
Edith Bellet-Amalric, Federico Panciera, Gilles Patriarche +5
The growth of ZnTe nanowires and ZnTe-CdTe nanowire heterostructures is studied by \emph{in situ} transmission electron microscopy. We describe the shape, and the change of shape,…
A High Throughput Study of both Compositionally Graded and Homogeneous Fe-Pt Thin Films
Yuan Hong, Isabelle de Moraes, Gabriel Gomez Eslava +7
Compositionally graded Fe-Pt thin films were prepared on stationary 100 mm Si substrates by magnetron sputtering a base target of Fe on which a piece of Pt is asymmetrically positi…
