Monolayers Grown by Molecular Beam Epitaxy on hBN
Julia Kucharek, Mateusz Raczyński, Rafał Bożek +9
A three-step process was developed for growing high-quality, optically uniform WSe2 monolayers by molecular beam epitaxy (MBE) with advantage of using hexagonal boron nitride (hBN)…
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…
Off-resonant photoluminescence spectroscopy of high-optical quality single photon emitters in GaN
Nilesh Dalla, Paweł Kulboka, Michał 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…
Carrier localization in defected areas of (Cd, Mn)Te quantum well investigated via Optically Detected Magnetic Resonance employed in the microscale
Amadeusz Dydniański, Aleksandra Łopion, Mateusz Raczyński +4
In this work, we study the impact of carrier localization on three quantities sensitive to carrier gas density at the micrometer scale: charged exciton (X+) oscillator strength, lo…
Single vanadium ion magnetic dopant in an individual CdTe/ZnTe quantum dot
Karolina Ewa Połczyńska, Tomasz Kazimierczuk, Piotr Kossacki +1
We present the basic properties of a new physical system: an individual V2+ ion embedded into an individual quantum dot. The system is realized utilizing molecular beam epitaxy and…
Colossal magneto-excitonic effects in 2D van der Waals magnetic semiconductor CrSBr
R. Komar, M. Goryca, A. Łopion +12
2D magnetic semiconductors, which intrinsically couple a rich landscape of magnetic orders with tightly bound electron-hole pairs (excitons), present an exciting platform to invest…
