Engineering 2D material exciton lineshape with graphene/h-BN encapsulation
Steffi Y. Woo, Fuhui Shao, Ashish Arora +20
Control over the optical properties of atomically thin two-dimensional (2D) layers, including those of transition metal dichalcogenides (TMDs), is needed for future optoelectronic…
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,…
Magnetooptics of layered two-dimensional semiconductors and heterostructures: progress and prospects
Ashish Arora
Beginning with the 'conventional' two-dimensional (2D) quantum wells (QWs) based on III-V and II-VI semiconductors in the 1970s, to the recent atomically-thin sheets of van der Waa…
Dark trions govern the temperature-dependent optical absorption and emission of doped atomically thin semiconductors
Ashish Arora, Nils Kolja Wessling, Thorsten Deilmann +7
We perform absorption and photoluminescence spectroscopy of trions in hBN-encapsulated WSe, WS, MoSe, and MoS monolayers, depending on temperature. The different tr…
