Bulk and single-layer 2H-NbSe₂ exhibit identical charge density wave order (CDW) with a quasi-commensurate 3 × 3 superlattice periodicity. Here we combine scanning tunnelling microscopy (STM) imaging at T = 1 K of 2H-NbSe₂ with first-principles density functional theory (DFT) calculations to investigate the structural atomic rearrangement of this CDW phase.

The interaction among magnetic moments screened by conduction electrons drives quantum phase transitions between magnetically ordered and heavy-fermion ground states. Here, starting from isolated magnetic impurities in the Kondo regime, we investigate the formation of the finite size analogue of a heavy Fermi liquid. [...]

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 Ignacio (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. [...]
