Journal ArticleDOI
Bandgap opening in graphene induced by patterned hydrogen adsorption
Richard Balog,Bjarke Jørgensen,Louis Nilsson,Mie Andersen,E. D. L. Rienks,Marco Bianchi,Mattia Fanetti,Erik Lægsgaard,Alessandro Baraldi,Alessandro Baraldi,Silvano Lizzit,Zeljko Sljivancanin,Flemming Besenbacher,Bjørk Hammer,Thomas Garm Pedersen,Philip Hofmann,Liv Hornekær +16 more
TL;DR: The existence of a bandgap opening in graphene is demonstrated, induced by the patterned adsorption of atomic hydrogen onto the Moiré superlattice positions of graphene grown on an Ir(111) substrate.
Journal ArticleDOI
Oxygen vacancies as active sites for water dissociation on rutile TiO(2)(110).
Renald Schaub,P. Thostrup,Núria López,Erik Lægsgaard,Ivan Stensgaard,Jens K. Nørskov,Flemming Besenbacher +6 more
TL;DR: Through an interplay between scanning tunneling microscopy experiments and density functional theory calculations, it is determined unambiguously the active surface site responsible for the dissociation of water molecules adsorbed on rutile TiO(2)(110).
Journal ArticleDOI
Atomic-scale structure of single-layer MoS2 nanoclusters
Stig Helveg,Jeppe V. Lauritsen,Erik Lægsgaard,Ivan Stensgaard,Jens K. Nørskov,Clausen Bjerne Steffen,Henrik Topsøe,Flemming Besenbacher +7 more
TL;DR: The STM gives the first real space images of the shape and edge structure of single-layer MoS2 nanoparticles synthesized on Au(111), and establishes a new picture of the active edge sites of the nanoclusters.
Journal ArticleDOI
Size-dependent structure of MoS2 nanocrystals.
Jeppe V. Lauritsen,Jakob Kibsgaard,Stig Helveg,Henrik Topsøe,Bjerne S. Clausen,Erik Lægsgaard,Flemming Besenbacher +6 more
TL;DR: The novel findings suggest that good size control during the synthesis of MoS2 nanostructures may be used for the production of chemically or optically active MoS1 nanomaterials with superior performance.
Journal ArticleDOI
Oxygen vacancies on TiO2(110) and their interaction with H2O and O2: A combined high-resolution STM and DFT study
Stefan Wendt,Renald Schaub,J. Matthiesen,Ebbe K. Vestergaard,Erik Wahlström,Maria Rasmussen,P. Thostrup,Luis M. Molina,Erik Lægsgaard,Ivan Stensgaard,Bjørk Hammer,Flemming Besenbacher +11 more
TL;DR: From an interplay between high-resolution scanning tunneling microscopy (STM) and density functional theory (DFT), the authors in this paper discuss the origin of various point defects on reduced rutile TiO2(1/1/0)-(1 × 1) surfaces.
