Excitonic Absorption Signatures of Twisted Bilayer WSe by Electron Energy-Loss Spectroscopy
Steffi Y. Woo, Alberto Zobelli, Robert Schneider +7
Moiré twist angle underpins the interlayer interaction of excitons in twisted van der Waals hetero- and homo-structures. The influence of twist angle on the excitonic absorption of…
High-performance broadband Faraday rotation spectroscopy of 2D materials and thin magnetic films
Benjamin Carey, Nils Kolja Wessling, Paul Steeger +8
We present a Faraday rotation spectroscopy (FRS) technique for measurements on the micron scale. Spectral acquisition speeds of many orders of magnitude faster than state-of-the-ar…
Substrate influence on transition metal dichalcogenide monolayer exciton absorption linewidth broadening
Fuhui Shao, Steffi Y. Woo, Nianjheng Wu +13
The excitonic states of transition metal dichacolgenide (TMD) monolayers are heavily influenced by their external dielectric environment based on the substrate used. In this work,…
