Photoelectron and electron microscopy investigation of laboratory grown Mg-silicate space dust analogues
Steffen Friis Holleufer, Mie Andersen, Frederik Granzow Doktor +9
The atomic structure at the surface of interstellar silicate dust particles likely plays a key role in a variety of chemical processes occurring in star- and planet-forming regions…
Silicon oxide nanoparticles grown on graphite by codeposition of the atomic constituents
Steffen Friis Holleufer, Alfred Hopkinson, Duncan S. Sutherland +4
Nanoscale silicate dust particles are the most abundant refractory component observed in the interstellar medium and thought to play a key role in catalysing the formation of compl…
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…
Monomeric, Two-Dimensionally Ordered WO Clusters on Anatase TiO(101)
Tao Xu, Kræn C. Adamsen, Hanne Falsig +4
We combined scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS) experiments with density functional theory (DFT) calculations to study dispersed tungsta…
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…
Single-layer MoS on Au(111): band gap renormalization and substrate interaction
Albert Bruix, Jill A. Miwa, Nadine Hauptmann +11
The electronic structure of epitaxial single-layer MoS on Au(111) is investigated by angle-resolved photoemission spectroscopy, scanning tunnelling spectroscopy, and first prin…
In Situ Detection of Active Edge Sites in Single-Layer MoS Catalysts
Albert Bruix, Henrik G. Füchtbauer, Anders K. Tuxen +6
MoS2 nanoparticles are proven catalysts for processes such as hydrodesulphurization and hydrogen evolution, but unravelling their atomic-scale structure under catalytic working con…
Synthesis of Epitaxial Single-Layer MoS on Au(111)
Signe S. Grønborg, Søren Ulstrup, Marco Bianchi +5
We present a method for synthesizing large area epitaxial single-layer MoS on the Au(111) surface in ultrahigh vacuum. Using scanning tunneling microscopy and low energy electr…
Growth and electronic structure of epitaxial single-layer WS on Au(111)
Maciej Dendzik, Matteo Michiardi, Charlotte Sanders +5
Large-area single-layer WS is grown epitaxially on Au(111) using evaporation of W atoms in a low pressure HS atmosphere. It is characterized by means of scanning tunneling…
Observation of Ultrafast Free Carrier Dynamics in Single Layer MoS
Antonija Grubišić Čabo, Jill A. Miwa, Signe S. Grønborg +11
The dynamics of excited electrons and holes in single layer (SL) MoS have so far been difficult to disentangle from the excitons that dominate the optical response of this mate…
Electronic Structure of Epitaxial Single-Layer MoS
Jill A. Miwa, Søren Ulstrup, Signe G. Sørensen +5
