Dimensional reduction, quantum Hall effect and layer parity in graphite films
Jun Yin, Sergey Slizovskiy, Yang Cao +13
The quantum Hall effect (QHE) originates from discrete Landau levels forming in a two-dimensional (2D) electron system in a magnetic field. In three dimensions (3D), the QHE is for…
Hybridized indirect excitons in MoS2/WS2 heterobilayers
Jonas Kiemle, Florian Sigger, Michael Lorke +5
Ensembles of indirect or interlayer excitons (IXs) are intriguing systems to explore classical and quantum phases of interacting bosonic ensembles. IXs are composite bosons that fe…
Magic Angle Spectroscopy
Alexander Kerelsky, Leo McGilly, Dante M. Kennes +9
The electronic properties of heterostructures of atomically-thin van der Waals (vdW) crystals can be modified substantially by Moiré superlattice potentials arising from an interla…
New generation of moiré superlattices in doubly aligned hBN/graphene/hBN heterostructures
Lujun Wang, Simon Zihlmann, Ming-Hao Liu +5
The specific rotational alignment of two-dimensional lattices results in a moiré superlattice with a larger period than the original lattices and allows one to engineer the electro…
Observation of Moiré Excitons in WSe2/WS2 Heterostructure Superlattices
Chenhao Jin, Emma C. Regan, Aiming Yan +10
Moiré superlattices provide a powerful tool to engineer novel quantum phenomena in two-dimensional (2D) heterostructures, where the interactions between the atomically thin layers…
Valley-dependent Exciton Fine Structure and Autler-Townes Doublets from Berry Phases in Monolayer Molybdenum Diselenide
Chaw-Keong Yong, M. Iqbal Bakti Utama, Chin Shen Ong +12
The Berry phase of Bloch states can have profound effects on electron dynamics lead to novel transport phenomena, such as the anomalous Hall effect and the valley Hall effect. Rece…
