Interfacial Oxidation Enables Charge-Transfer Contacts and Degenerate n-Doping in Monolayer MoS
Marco Bianchi, Daniel Lizzit, Alberto Turoldo +7
High contact resistance remains a central obstacle to the integration of two-dimensional (2D) semiconductors in electronic devices. Recent advances have demonstrated that contact p…
Electronic structure of Graphene/Co interfaces
Daniela Pacilé, Simone Lisi, Iolanda Di Bernardo +12
Photoemission, from core levels and valence band, and low-energy electron diffraction (LEED) have been employed to investigate the electronic and structural properties of novel gra…
On-surface dehydrogenative lateral homo-coupling and aromatization of n-octane on Pt(111)
D. Arribas, E. Tosi, V. Villalobos-Vilda +14
Aliphatic hydrocarbons, such as normal alkanes, constitute a naturally abundant source of carbon atoms. Of special interest is the formation of cyclic and aromatic products from al…
Interfacial two-dimensional oxide enhances photocatalytic activity of graphene/titania via electronic structure modification
Dario De Angelis, Francesco Presel, Naila Jabeen +8
A two-dimensional layer of oxide reveals itself as a essential element to drive the photocatalytic activity in a nanostructured hybrid material, which combines high-quality epitaxi…
Probing the Atomic Arrangement of Sub-Surface Dopants in a Silicon Quantum Device Platform
Håkon I. Røst, Ezequiel Tosi, Frode S. Strand +4
High-density structures of sub-surface phosphorus dopants in silicon continue to garner interest as a silicon-based quantum computer platform, however, a much-needed confirmation o…
Ultrafast electronic line width broadening in the C 1s core level of graphene
Davide Curcio, Sahar Pakdel, Klara Volckaert +31
Core level binding energies and absorption edges are at the heart of many experimental techniques concerned with element-specific structure, electronic structure, chemical reactivi…
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…
Electron-phonon coupling in single-layer MoS2
Sanjoy K. Mahatha, Arlette S. Ngankeu, Nicki Frank Hinsche +15
The electron-phonon coupling strength in the spin-split valence band maximum of single-layer MoS is studied using angle-resolved photoemission spectroscopy and density function…
Growth and Structure of Singly-Oriented Single-Layer Tungsten Disulfide on Au(111)
Luca Bignardi, Daniel Lizzit, Harsh Bana +14
We present a complete characterisation at the nanoscale of the growth and structure of single-layer tungsten disulfide (WS) epitaxially grown on Au(111). Following the growth p…
Novel single-layer vanadium sulphide phases
Fabian Arnold, Raluca-Maria Stan, Sanjoy K. Mahatha +15
VS2 is a challenging material to prepare stoichiometrically in the bulk, and the single layer has not been successfully isolated before now. Here we report the first realization of…
Epitaxial Growth of Single-Orientation High-Quality MoS Monolayers
Harsh Bana, Elisabetta Travaglia, Luca Bignardi +16
We present a study on the growth and characterization of high-quality single-layer MoS with a single orientation, i.e. without the presence of mirror domains. This single orien…
Photoemission Investigation of Oxygen Intercalated Epitaxial Graphene on Ru(0001)
Søren Ulstrup, Paolo Lacovig, Fabrizio Orlando +9
We study the formation of epitaxial graphene on Ru(0001) using fast x-ray photoelectron spectroscopy during the growth process. The assignment of different C 1s and Ru 3d core leve…
Electron-phonon coupling in the spin-split valence band of single layer WS

The absence of inversion symmetry leads to a strong spin-orbit splitting of the upper valence band of semiconducting single layer transition metal dichalchogenides such as MoS…
Disentangling Vacancy Oxidation on Metallicity-Sorted Carbon Nanotubes
Duncan J. Mowbray, Alejandro Pérez Paz, Georgina Ruiz-Soria +9
Pristine single-walled carbon nanotubes (SWCNTs) are rather inert to O and N, which for low doses chemisorb only on defect sites or vacancies of the SWCNTs at the ppm level…
Transfer-free electrical insulation of epitaxial graphene from its metal substrate
Silvano Lizzit, Rosanna Larciprete, Paolo Lacovig +8
High-quality, large-area epitaxial graphene can be grown on metal surfaces but its transport properties cannot be exploited because the electrical conduction is dominated by the su…
