Excitons in epitaxially grown WS2 on Graphene: a nanometer-resolved EELS and DFT study
Max Bergmann, Jürgen Belz, Oliver Maßmeyer +12
In this study, we investigate excitonic properties of epitaxially grown WS2, which is of particular interest for various applications due to its potential for upscaling to wafer si…
A Small Step for Epitaxy, a Large Step Towards Twist Angle Control in 2D Heterostructures
Oliver Maßmeyer, Jürgen Belz, Badrosadat Ojaghi Dogahe +9
Two-dimensional (2D) materials have received a lot of interest over the past decade. Especially van der Waals (vdW) 2D materials, such as transition metal dichalcogenides (TMDCs),…
Coherent optical and acoustic phonons generated at lattice-matched GaP/Si(001) heterointerfaces
Kunie Ishioka, Andreas Beyer, Wolfgang Stolz +4
Thin GaP films can be grown on an exact Si(001) substrate with nearly perfect lattice match. We perform all-optical pump-probe measurements to investigate the ultrafast electron-ph…
Sub-picosecond acoustic pulses at buried GaP/Si interfaces
Kunie Ishioka, Avinash Rustagi, Andreas Beyer +5
We report on the optical generation and detection of ultrashort acoustic pulses that propagate in three-dimensional semiconductor crystals. Photoexcitaiton of lattice-matched GaP l…
