Valley-magnetophonon resonance for interlayer excitons

D. S. Smirnov, J. Holler, M. Kempf +8

Heterobilayers consisting of MoSe and WSe monolayers can host optically bright interlayer excitons with intriguing properties such as ultralong lifetimes and pronounced cir…

Low-frequency Raman scattering in WSe-MoSe heterobilayers: Evidence for atomic reconstruction

Johannes Holler, Sebastian Meier, Michael Kempf +5

We investigate WSe-MoSe heterobilayers with different twist angles between the two layers, by low-frequency Raman scattering. In sufficiently aligned samples with…

Air tightness of hBN encapsulation and its impact on Raman spectroscopy of van der Waals materials

Johannes Holler, Lorenz Bauriedl, Tobias Korn +8

Raman spectroscopy is a precious tool for the characterization of van der Waals materials, e.g. for the determination of the layer number in thin exfoliated flakes. For sensitive m…

Dielectric Engineering of Electronic Correlations in a van der Waals Heterostructure

Philipp Steinleitner, Philipp Merkl, Alexander Graf +10

Heterostructures of van der Waals bonded layered materials offer unique means to tailor dielectric screening with atomic-layer precision, opening a fertile field of fundamental res…

Exciton diffusion and halo effects in monolayer semiconductors

Marvin Kulig, Jonas Zipfel, Philipp Nagler +6

We directly monitor exciton propagation in freestanding and SiO2-supported WS2 monolayers through spatially- and time-resolved micro-photoluminescence under ambient conditions. We…

Characterization of highly crystalline lead iodide nanosheets prepared by room-temperature solution processing

Riccardo Frisenda, Joshua O. Island, Jose L. Lado +15

Two-dimensional semiconducting materials are particularly appealing for many applications. Although theory predicts a large number of two-dimensional materials, experimentally only…
