Demonstrating Kondo behavior by temperature-dependent scanning tunneling spectroscopy
Elia Turco, Markus Aapro, Somesh C. Ganguli +9
The Kondo effect describes the scattering of conduction electrons by magnetic impurities, manifesting as an electronic resonance at the Fermi energy with a distinctive temperature…
Tailoring magnetism of nanographenes via tip-controlled dehydrogenation
Chenxiao Zhao, Qiang Huang, Leoš Valenta +10
Atomically precise graphene nanoflakes, called nanographenes, have emerged as a promising platform to realize carbon magnetism. Their ground state spin configuration can be anticip…
Charge State-Dependent Symmetry Breaking of Atomic Defects in Transition Metal Dichalcogenides
Feifei Xiang, Lysander Huberich, Preston A. Vargas +11
The functionality of atomic quantum emitters is intrinsically linked to their host lattice coordination. Structural distortions that spontaneously break the lattice symmetry strong…
On-surface synthesis and characterization of Teranthene and Hexanthene: Ultrashort graphene nanoribbons with mixed armchair and zigzag edges
Gabriela Borin Barin, Marco Di Giovannantonio, Thorsten G. Lohr +8
Graphene nanoribbons (GNRs) exhibit a broad range of physicochemical properties that critically depend on their width and edge topology. While the chemically stable GNRs with armch…
Exchange interactions and intermolecular hybridization in a spin-1/2 nanographene dimer
N. Krane, E. Turco, A. Bernhardt +8
Phenalenyl is a radical nanographene with triangular shape that hosts an unpaired electron with spin S = 1/2. The open-shell nature of phenalenyl is expected to be retained in cova…
Quantifying Alignment and Quality of Graphene Nanoribbons: A Polarized Raman Spectroscopy Approach
Rimah Darawish, Jan Overbeck, Klaus Müllen +4
Graphene nanoribbons (GNRs) are atomically precise stripes of graphene with tunable electronic properties, making them promising for room-temperature switching applications like fi…
MoRe Electrodes with 10-nm Nanogaps for Electrical Contact to Atomically Precise Graphene Nanoribbons
Damian Bouwmeester, Talieh S. Ghiasi, Gabriela Borin Barin +4
Atomically precise graphene nanoribbons (GNRs) are predicted to exhibit exceptional edge-related properties, such as localized edge states, spin polarization, and half-metallicity.…
Platinum contacts for 9-atom-wide armchair graphene nanoribbons
Chunwei Hsu, Michael Rohde, Gabriela Borin Barin +7
Creating a good contact between electrodes and graphene nanoribbons (GNRs) has been a longstanding challenge in searching for the next GNR-based nanoelectronics. This quest require…
