Spatially-Resolved Band Gap and Dielectric Function in 2D Materials from Electron Energy Loss Spectroscopy
Abel Brokkelkamp, Jaco ter Hoeve, Isabel Postmes +6
The electronic properties of two-dimensional (2D) materials depend sensitively on the underlying atomic arrangement down to the monolayer level. Here we present a novel strategy fo…
Position-dependence of valley polarization and valley coherence of WS2 monolayer flakes
Irina Komen, Sabrya E. van Heijst, Sonia Conesa-Boj +1
Chiral interaction between light and two-dimensional transition metal dichalcogenides (2D-TMDs) has recently drawn enormous scientific attention. The optical selection rules of the…
Illuminating the electronic properties of WS polytypism with electron microscopy
Sabrya E. van Heijst, Masaki Mukai, Eiji Okunishi +5
Tailoring the specific stacking sequences (polytypes) of layered materials represents a powerful strategy to identify and design novel physical properties. While nanostructures bui…
Charting the low-loss region in Electron Energy Loss Spectroscopy with machine learning
Laurien I. Roest, Sabrya E. van Heijst, Louis Maduro +2
Exploiting the information provided by electron energy-loss spectroscopy (EELS) requires reliable access to the low-loss region where the zero-loss peak (ZLP) often overwhelms the…
Robust fabrication of large-area in- and out-of-plane cross-section samples of layered materials with ultramicrotomy
M. O. Cichocka, M. Bolhuis, S. E. van Heijst +1
Layered materials (LMs) such as graphene or MoS have recently attracted a great deal of interest. These materials offer unique functionalities due to their structural anisotrop…
Metallic edge states in zig-zag vertically-oriented MoS2 nanowalls
Miguel Tinoco, Louis Maduro, Sonia Conesa-Boj
The remarkable properties of layered materials such as MoS2 strongly depend on their dimensionality. Beyond manipulating their dimensions, it has been predicted that the electronic…
