Distinct Magneto-Optical Response of Frenkel and Wannier Excitons in CrSBr
Maciej Smiertka, Michal Rygala, Katarzyna Posmyk +10
This study shows that CrSBr hosts Frenkel-like and Wannier-Mott-like excitons whose distinct spatial character explains their contrasting sensitivity to magnetic order and lattice…
Approaching the Intrinsic Properties of Moiré Structures Using Atomic Force Microscopy Ironing
Swaroop Kumar Palai, Mateusz Dyksik, Nikodem Sokolowski +12
Stacking monolayers of transition metal dichalcogenides (TMDs) has led to the discovery of a plethora of new exotic phenomena, resulting from moiré pattern formation. Due to the at…
Quadrupolar Excitons in MoSe Bilayers
Jakub Jasiński, Joakim Hagel, Samuel Brem +11
The quest for platforms to generate and control exotic excitonic states has greatly benefited from the advent of transition metal dichalcogenide (TMD) monolayers and their heterost…
Phonon-bottleneck enhanced exciton emission in 2D perovskites
Joshua J. P. Thompson, Mateusz Dyksik, Paulina Peksa +8
Layered halide perovskites exhibit remarkable optoelectronic properties and technological promise, driven by strongly bound excitons. The interplay of spin-orbit and exchange coupl…
Phase Transition Induced Carrier Mass Enhancement in 2D Ruddlesden-Popper Perovskites
Michal Baranowski, Szymon J. Zelewski, Mikael Kepenekian +10
There is a variety of possible ways to tune the optical properties of 2D perovskites, though the mutual dependence between different tuning parameters hinders our fundamental under…
Giant Fine Structure Splitting of the Bright Exciton in a Bulk MAPbBr Single Crystal
Michal Baranowski, Krzysztof Galkowski, Alessandro Surrente +13
Exciton fine structure splitting in semiconductors reflects the underlying symmetry of the crystal and quantum confinement. Since the latter factor strongly enhances the exchange i…
Symmetry breakdown in franckeite: spontaneous strain, rippling and interlayer moiré
Riccardo Frisenda, Gabriel Sanchez-Santolino, Nikos Papadopoulos +9
Franckeite is a naturally occurring layered mineral with a structure composed of alternating stacks of SnS2-like and PbS-like layers. Although this superlattice is composed of a se…
Moiré Intralayer Excitons in a MoSe/MoS Heterostructure
Nan Zhang, Alessandro Surrente, Michal Baranowski +4
Spatially periodic structures with a long range period, referred to as moiré pattern, can be obtained in van der Waals bilayers in the presence of a small stacking angle or of latt…
Intervalley Scattering of Interlayer Excitons in a MoS/MoSe/MoS Heterostructure in High Magnetic Field
Alessandro Surrente, Lukasz Klopotowski, Nan Zhang +9
Degenerate extrema in the energy dispersion of charge carriers in solids, also referred to as valleys, can be regarded as a binary quantum degree of freedom, which can potentially…
Observation of A Raman mode splitting in few layers black phosphorus encapsulated with hexagonal boron nitride
J. M. Urban, M. Baranowski, A. Surrente +8
We investigate the impact of the encapsulation with hexagonal boron nitride (h-BN) on the Raman spectrum of few layer black phosphorus. The encapsulation results in a significant r…
Probing the inter-layer exciton physics in a MoS/MoSe/MoS van der Waals heterostructure
M. Baranowski, A. Surrente, L. Klopotowski +9
Stacking atomic monolayers of semiconducting transition metal dichalcogenides (TMDs) has emerged as an effective way to engineer their properties. In principle, the staggered band…
Dark excitons and the elusive valley polarization in transition metal dichalcogenides
M. Baranowski, A. Surrente, D. K. Maude +7
A rate equation model for the dark and bright excitons kinetics is proposed which explains the wide variation in the observed degree of circular polarization of the PL emission in…
