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…
All field emission experiments are noisy, {\ldots} are any meaningful?
Anthony Ayari, Pascal Vincent, Sorin Perisanu +2
Representing field emission data on a Fowler--Nordheim plot is both very common and strongly not recommended. It leads to a spurious estimation of the emitter parameters despite a…
All field emission models are wrong, but are any of them useful?
Anthony Ayari, Pascal Vincent, Sorin Perisanu +2
Field emission data are often represented on a Fowler--Nordheim plot but a new empirical equation has been recently proposed to better analyze experiments. Such an equation is base…
Optical net gain measurement on AlGaN/GaN multi-quantum well
Quang Minh Thai, Sergi Cuesta, Lou Denaix +5
We present net gain measurements at room temperature in AlGaN/GaN 10-period multi-quantum well emitting at 367 nm, using the variable stripe length method. Measur…
Femtosecond Laser Induced Resonant Tunneling in an Individual Quantum Dot Attached to a Nanotip
Maxime Duchet, Sorin Perisanu, Stephen Purcell +6
Quantized nano-objects offer a myriad of exciting possibilities for manipulating electrons and light that impact photonics, nanoelectronics, and quantum information. In this contex…
AlGaN/GaN asymmetric graded-index separate confinement heterostructures designed for electron-beam pumped UV lasers
Sergi Cuesta, Yoann Curé, Fabrice Donatini +9
We present a study of undoped AlGaN/GaN separate confinement heterostructures designed to operate as electron beam pumped ultraviolet lasers. We discuss the effect of spontaneous a…
