Direct visualization and control of SrOx segregation on semiconducting Nb doped SrTiO3 (100) surface
Hyang Keun Yoo, Daniel Schwarz, Soren Ulstrup +6
We investigated how SrOx segregates on a Nb doped SrTiO3 (100) surface by in air annealing. Using atomic force and photoemission electron microscopes, we can directly visualize the…
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…
Electronic Structure of Exfoliated and Epitaxial Hexagonal Boron Nitride
Roland J. Koch, Jyoti Katoch, Simon Moser +6
Hexagonal boron nitride (hBN) is an essential component in van der Waals heterostructures as it provides high quality and weakly interacting interfaces that preserve the electronic…
Spatially Resolved Electronic Properties of Single-Layer WS on Transition Metal Oxides
Søren Ulstrup, Jyoti Katoch, Roland J. Koch +10
There is a substantial interest in the heterostructures of semiconducting transition metal dichalcogenides (TMDCs) amongst each other or with arbitrary materials, through which the…
