Spectroscopic Evaluation of Charge-transfer Doping and Strain in Graphene/MoS2 Heterostructures
Rahul Rao, Ahmad E. Islam, Simranjeet Singh +4
It is important to study the van der Waals interface in emerging vertical heterostructures based on layered two-dimensional (2D) materials. Being atomically thin, 2D materials are…
Direct observation of minibands in twisted heterobilayers
Søren Ulstrup, Roland J. Koch, Simranjeet Singh +8
Stacking two-dimensional (2D) van der Waals materials with different interlayer atomic registry in a heterobilayer causes the formation of a long-range periodic superlattice that m…
Imaging microscopic electronic contrasts at the interface of single-layer WS with oxide and boron nitride substrates
Søren Ulstrup, Roland J. Koch, Daniel Schwarz +7
The electronic properties of devices based on two-dimensional materials are significantly influenced by interactions with substrate and electrode materials. Here, we use photoemiss…
