Ultraviolet Photodetectors based on GaN and AlGaN/AlN Nanowire Ensembles: Effects of Planarization with Hydrogen Silsesquioxane and Nanowire Architecture
E. Akar, I. Dimkou, A. Ajay +2
The interest in nanowire photodetectors stems from their potential to improve the performance of a variety of devices, including solar cells, cameras, sensors, and communication sy…
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…
Solubility limit of Ge Dopants in AlGaN: a Chemical and Microstructural Investigation down to the Nanoscale
C. Bougerol, E. Robin, E. Di Russo +5
Attaining low resistivity AlGaN layers is the keystone to improve the efficiency of light emitting devices in the ultraviolet spectral range. Here, we present a microstructural ana…
Highly transparent contacts to the 1D hole gas in ultra-scaled Ge/Si core/shell nanowires
Masiar Sistani, Jovian Delaforce, Roman Kramer +10
Semiconductor-superconductor hybrid systems have outstanding potential for emerging high-performance nanoelectronics and quantum devices. However, critical to their successful appl…
In-situ high resolution TEM observation of Aluminum solid-state diffusion in Germanium nanowires: fabricating sub-10 nm Ge quantum dots
M. Luong, E. Robin, N. Pauc +6
Aluminum-germanium nanowires (NWs) thermal activated solid state reaction is a promising system as very sharp and well defined one dimensional contacts can be created between a met…
Electrical and Optical Properties of Heavily Ge-Doped AlGaN
R. Blasco, A. Ajay, E. Robin +7
We report the effect of germanium as n-type dopant on the electrical and optical properties of AlxGa1-xN layers grown by plasma assisted molecular-beam epitaxy. The Al content has…
