Electron-phonon coupling across the TMD/hBN van der Waals interface
G. Gatti, C. Berthod, J. Issing +18
Many-body interactions can couple electronic states in one layer with collective excitations in the adjacent layer, providing a route to tailor properties of heterostructures. Howe…
Spin-Valley Relaxation of Rydberg Excitons
V. Jindal, K. Mourzidis, M. Semina +8
Rydberg excitons, characterized by large spatial extension and reduced electron-hole overlap, must have a spin-valley dynamics different from that of ground state excitons. Here we…
Spectroscopy of Wigner crystal polarons in an atomically thin semiconductor
L. Wang, F. Menzel, F. Pichler +5
Strongly interacting electrons in two-dimensional systems can spontaneously break translational symmetry, forming a periodic Wigner crystal. Although these crystals have been reali…
Probing moire excitons in MoSe2/WSe2 heterobilayers by combined micro-photoluminescence and lateral force microscopy
L. Caussou, H. Moutaabbid, M. Bernard +6
We study interlayer excitons in MoSe2/WSe2 heterobilayers, by combining lateral force microscopy and micro-photoluminescence spectroscopy. This allows us to correlate the spatial p…
Dielectric environment engineering via 2D material heterostructure formation on hybrid photonic crystal nanocavity
C. F. Fong, D. Yamashita, N. Fang +5
Hybrid integration of two-dimensional (2D) materials with nanophotonic platforms has enabled compact optoelectronic devices by leveraging the unique optical and electronic properti…
