Optical properties of atomically thin transition metal dichalcogenides: Observations and puzzles
M. Koperski, M. R. Molas, A. Arora +4
Recent results on the optical properties of mono- and few-layers of semiconducting transition metal dichalcogenides are reviewed. Experimental observations are presented and discus…
Brightening of dark excitons in monolayers of semiconducting transition metal dichalcogenides
M. R. Molas, C. Faugeras, A. O. Slobodeniuk +4
We present low temperature magneto-photoluminescence experiments which demonstrate the brightening of dark excitons by an in-plane magnetic field applied to monolayers of diffe…
Resonant quenching of Raman scattering due to out-of-plane A/A' modes in few-layer MoTe
K. Gołasa, M. Grzeszczyk, M. R. Molas +6
Temperature-dependent (5 K to 300 K) Raman scattering study of A/A' phonon modes in mono-layer (1L), bilayer (2L), trilayer (3L), and tetralayer (4L) MoTe is reporte…
Experimental approval of the extended flat bands and gapped subbands in rhombohedral multilayer graphene
Y. Henni, H. P. Ojeda Collado, K. Nogajewski +6
Graphene layers are known to stack in two stable configurations, namely ABA or ABC stacking, with drastically distinct electronic properties. Unlike the ABA stacking, little has be…
Energy spectrum of confined positively charged excitons in single quantum dots
M. R. Molas, A. Wojs, A. A. L. Nicolet +2
A theoretical model, which relates the binding energy of a positively charged exciton in a quantum dot with the confinement energy is presented. It is shown that the binding energy…
The excited spin-triplet state of a charged exciton in quantum dots
M. R. Molas, A. A. L. Nicolet, B. Pietka +2
We report on single-object spectroscopic studies of a characteristic set of three resonances which appear in GaAlAs/AlAs quantum dot structures. The experiments included the photol…
