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…
Exciton coherence propagation measured with non-local four-wave mixing micro-spectroscopy
Mateusz RaczyÅski, Amadeusz DydniaÅski, Karolina Ewa PoÅczyÅska +8
Coherence transfer is a multi-disciplinary topic of interest, including chemistry, biology and physics. In quantum technologies, achieving non-local coherent coupling between solid…
Hole to Electron Crossover in a (Cd,Mn)Te Quantum Well through Surface Metallization
Amadeusz DydniaÅski, Mateusz RaczyÅski, Aleksandra Åopion +5
In this work we look into how the contact material influences the local charge properties of a p-type CdTe-based quantum well. We study five metals deposited as 10 nm layers on the…
Magnetic field induced polarization enhancement in the photoluminescence of MBE-grown WSe layers
Maksymilian Kuna, Mateusz RaczyÅski, Julia Kucharek +5
We report an experimental study of the magnetic-field dependence of the optically pumped valley polarization in an epitaxial tungsten diselenide (WSe) monolayer grown by molecu…
