Efficient Quasi-Resonant, Polarization-Selective Excitation of GaN Quantum Emitters
Nilesh Dalla, PaweÅ Kulboka, MichaÅ Kobecki +6
Defect centers in GaN emerge as bright sources of single-photons which recently have been demonstrated to optically interface a localized spin. However, the structure and compositi…

On the origin of the E1 electron trap level in GaN and dilute AlxGa1-xN films
Piotr Kruszewski, Jose Coutinho, Vladimir P. Markevich +6
The results of high-resolution Laplace deep-level transient spectroscopy (L-DLTS) measurements applied to the E1 and FeGa electron traps in dilute AlxGa1-xN films (x = 0.063), grow…

Off-resonant photoluminescence spectroscopy of high-optical quality single photon emitters in GaN
Nilesh Dalla, PaweÅ Kulboka, MichaÅ Kobecki +5
In this work, we analyze the relevance of excitation parameters on the emission from single-photon emitting defect centers in GaN. We investigate the absorption spectrum of differe…
