Identifying the mechanism of single-domain single-layer MoS2 growth on Au(111)
Moritz Ewert, Lars Buß, Jeppe V. Lauritsen +2
The nucleation and growth of single-layer molybdenum disulfide single domain islands is investigated by in situ low-energy electron microscopy. We study the growth of micron-sized…
Electronic Properties of Single-Layer CoO/Au(111)
Ann Julie U. Holt, Sahar Pakdel, Jonathan Rodríguez-Fernández +11
We report direct measurements via angle-resolved photoemission spectroscopy (ARPES) of the electronic dispersion of single-layer CoO. The Fermi contour consists of a large hole…
Spectroscopic view of ultrafast charge carrier dynamics in single- and bilayer transition metal dichalcogenide semiconductors
P. Majchrzak, K. Volckaert, A. G. Cabo +24
The quasiparticle spectra of atomically thin semiconducting transition metal dichalcogenides (TMDCs) and their response to an ultrafast optical excitation critically depend on inte…
Size-dependent phase transitions in MoS2 nanoparticles controlled by a metal substrate
Albert Bruix, Jeppe Vang Lauritsen, Bjørk Hammer
Nanomaterials based on MoS2 are remarkably versatile; MoS2 nanoparticles are proven catalysts for processes such as hydrodesulphurization and the hydrogen evolution reaction, and t…
Ultrafast Band Structure Control of a Two-Dimensional Heterostructure
Søren Ulstrup, Antonija Grubišić Čabo, Jill A. Miwa +12
The electronic structure of two-dimensional (2D) semiconductors can be significantly altered by screening effects, either from free charge carriers in the material itself, or by en…
