Ultralow-Tensile Strain Enables Exciton Funneling and Energy Transfer to Boost MoSe2 Photoluminescence Quantum Yield
Gayatri, Mehdi Arfaoui, Debashish Das +14
Strain engineering is a powerful route for controlling the exciton dynamics in van der Waals (vdW) heterostructures (HSs). The interlayer energy transfer (ET) process is another ke…
Efficient Quasi-Resonant, Polarization-Selective Excitation of GaN Quantum Emitters
Nilesh Dalla, Paweł Kulboka, Michał 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…
Hole to Electron Crossover in a (Cd,Mn)Te Quantum Well through Surface Metallization
Amadeusz Dydniański, Mateusz Raczyński, Aleksandra Łopion +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 Raczyński, 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…
Fast Interlayer Energy Transfer from the Lower Bandgap MoS2 to the Higher Bandgap WS2
Gayatri, Mehdi Arfaoui, Debashish Das +9
Energy transfer (ET) is a dipole-dipole interaction, mediated by the virtual photon. Traditionally, ET happens from the higher (donor) to lower bandgap (acceptor) material. However…
Photoluminescence efficiency of MBE-grown MoSe monolayers featuring sharp excitonic lines and diverse grain structures
Mateusz Raczyński, Julia Kucharek, Kacper Oreszczuk +7
Recent studies have demonstrated that using h-BN as a substrate for the growth of transition metal dichalcogenides can significantly reduce excitonic linewidths. However, many othe…
