Probing Dielectric Screening in van der Waals Heterostructures via Pressure-Tuned Exciton Rydberg Series
Shalini Badola, Adlen Smiri, Thomas Pelini +7
Excitons in two-dimensional semiconductors are directly exposed to the environment and are sensitive to the dielectric properties of their surrounding. Here, we show that the Rydbe…
Sub-nm range momentum-dependent exciton transfer from a 2D semiconductor to graphene
Aditi Raman Moghe, Delphine Lagarde, Sotirios Papadopoulos +11
Heterostructures made from atomically thin semiconductors (here MoSe) and graphene are uniquely poised to investigate photoinduced charge and energy transfer in the 2D limit. H…
Sub-diffraction-resolved spatial distribution of emitting excitons in STM-induced luminescence of 2D semiconductors via Richardson-Lucy deconvolution
Elysé Laurent, Ricardo Javier Peña Román, Sarah Miller +7
Using scanning tunneling microscopy-induced luminescence (STML), the optical properties of two-dimensional (2D) semiconductors may be investigated at the nanoscale. This is possibl…
Symmetry-dependent dielectric screening of optical phonons in monolayer graphene
Loïc Moczko, Sven Reichardt, Aditya Singh +13
Quantised lattice vibrations (i.e., phonons) in solids are robust and unambiguous fingerprints of crystal structures and of their symmetry properties. In metals and semimetals, str…
Room-Temperature Anomalous Hall Effect in Graphene in Interfacial Magnetic Proximity with EuO Grown by Topotactic Reduction
Satakshi Pandey, Simon Hettler, Raul Arenal +6
We show that thin layers of EuO, a ferromagnetic insulator, can be achieved by topotactic reduction under titanium of a Eu2O3 film deposited on top of a graphene template. The redu…
