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…
Landau level spectroscopy of valence bands in HgTe quantum wells: Effects of symmetry lowering
L. S. Bovkun, A. V. Ikonnikov, V. Ya. Aleshkin +8
Landau level spectroscopy has been employed to probe the electronic structure of the valence band in a series of p-type HgTe/HgCdTe quantum wells with both normal and inverted orde…
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…
Magnetic-field driven ambipolar quantum Hall effect in epitaxial graphene close to the charge neutrality point
A. Nachawaty, M. Yang, W. Desrat +7
We have investigated the disorder of epitaxial graphene close to the charge neutrality point (CNP) by various methods: i) at room temperature, by analyzing the dependence of the re…
Single Photon Emitters in Boron Nitride: More Than a Supplementary Material
Maciej Koperski, Karol Nogajewski, Marek Potemski
We present comprehensive optical studies of recently discovered single photon sources in boron nitride, which appear in form of narrow lines emitting centres. Here, we aim to compa…
Raman scattering of graphene based systems in high magnetic fields
C. Faugeras, M. Orlita, M. Potemski
We review the different results obtained in the last decade in the field of Raman scattering of graphene based systems, with an applied magnetic field. Electronic properties of gra…
Optical response of monolayer, few-layer and bulk tungsten disulfide
Maciej R. Molas, Karol Nogajewski, Artur O. Slobodeniuk +3
We present a comprehensive optical study of thin films of tungsten disulfide (WS) with layer thicknesses ranging from mono- to octalayer and in the bulk limit. It is shown that…
Ultrahigh magnetic field spectroscopy reveals the band structure of the 3D topological insulator BiSe
A. Miyata, Z. Yang, A. Surrente +7
We have investigated the band structure at the point of the three-dimensional (3D) topological insulator BiSe using magneto-spectroscopy over a wide range of energies (…
Influence of nonequilibrium phonons on the amplitude of magnetoquantum oscillations in the point-contact resistance
N. L. Bobrov, J. A. Kokkedee, N. N. Gribov +2
For metallic point contacts with Be and Al the magnetoquantum oscillations in the contact resistance have been investigated as a function of the applied voltage over the contact. F…
Charged excitons in monolayer WSe: experiment and theory
E. Courtade, M. Semina, M. Manca +13
Charged excitons, or X-trions, in monolayer transition metal dichalcogenides have binding energies of several tens of meV. Together with the neutral exciton X they domi…
Revealing large-scale homogeneity and trace impurity sensitivity of GaAs nanoscale membranes
