26 p, 1.8 MB Growth of Twin-Free and Low-Doped Topological Insulators on BaF2(111) / Bonell, Frédéric (Institut Català de Nanociència i Nanotecnologia) ; González Cuxart, Marc (Institut Català de Nanociència i Nanotecnologia) ; Song, Kenan (Institut Català de Nanociència i Nanotecnologia) ; Robles, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Ordejon, Pablo (Institut Català de Nanociència i Nanotecnologia) ; Roche, Stephan (Institut Català de Nanociència i Nanotecnologia) ; Mugarza, Aitor (Institut Català de Nanociència i Nanotecnologia) ; Valenzuela, Sergio O. (Institut Català de Nanociència i Nanotecnologia) ; Universitat Autònoma de Barcelona
We demonstrate the growth of twin-free BiTe and SbTe topological insulators by molecular beam epitaxy and a sizable reduction of the twin density in BiSe on lattice-matched BaF(111) substrates. Using X-ray diffraction, electron diffraction and atomic force microscopy, we systematically investigate the parameters influencing the formation of twin domains and the morphology of the films, and show that Se- and Te-based alloys differ by their growth mechanism.

The dehydrogenation and dechlorination of FeOEP-Cl on Cu(111) has been studied in detail by scanning tunneling microscopy. Although, it is not possible to follow the reaction of an individual molecule, the complete pathway of the reaction with 22 inequivalent intermediate states and the rates of the involved processes are revealed.

12 p, 1.6 MB Spin-polarised edge states in atomic Mn chains supported on Cu2N/Cu (100) / Choi, Deung-Jang (CIC Nano GUNE (Sant Sebastià, País Basc)) ; Robles, Roberto (Institut Català de Nanociència i Nanotecnologia) ; Gauyacq, Jean-Pierre (Université Paris-Saclay. Institut des Sciences Moléculaires d'Orsay) ; Rubio-Verdú, Carmen (CIC Nano GUNE (Sant Sebastià, País Basc)) ; Lorente Palacios, Nicolás (Centro de Física de Materiales (Sant Sebastià, País Basc)) ; Pascual, José I. (Ikerbasque. Basque Foundation for Science (Bilbao, País Basc))
Scanning tunnelling microscopy and density functional theory studies of manganese chains adsorbed on CuN/Cu (100) reveal an unsuspected electronic edge state at ∼ 1 eV above the Fermi energy. This Tamm-like state is strongly localised to the terminal Mn atoms of the chain and fully spin polarised. [...]

A self-assembled monolayer of mercaptobenzoic acid (MBA) on Au(110) is investigated with scanning tunneling and atomic force microscopy (STM and AFM) and density functional calculations. High-resolution AFM images obtained with metallic tips show clear contrasts between oxygen atoms and phenyl moieties. [...]
