One-dimensional carbon nanostructures with periodic graphitic nitrogen substitution
Nicolò Bassi, Shantanu Mishra, Zheng Zhang +8
Heteroatom substitution is a powerful route to tune the chemical and electronic properties of carbon nanomaterials. In particular, replacement of an sp2 hybridized carbon atom in t…
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…
Bistability between -diradical open-shell and closed-shell states in indeno[1,2-a]fluorene
Shantanu Mishra, Manuel Vilas-Varela, Leonard-Alexander Lieske +7
Indenofluorenes are non-benzenoid conjugated hydrocarbons that have received great interest owing to their unusual electronic structure and potential applications in non-linear opt…
Twisted bilayer zigzag-graphene nanoribbon junctions with tunable edge states
Dongfei Wang, De-Liang Bao, Qi Zheng +14
Stacking two-dimensional layered materials such as graphene and transitional metal dichalcogenides with nonzero interlayer twist angles has recently become attractive because of th…
Growth optimization and device integration of narrow-bandgap graphene nanoribbons
Gabriela Borin Barin, Qiang Sun, Marco Di Giovannantonio +26
The electronic, optical and magnetic properties of graphene nanoribbons (GNRs) can be engineered by controlling their edge structure and width with atomic precision through bottom-…
Non-benzenoid high-spin polycyclic hydrocarbons generated by atom manipulation
Shantanu Mishra, Shadi Fatayer, Saleta Fernandez +3
We report the on-surface synthesis of a non-benzenoid triradical through dehydrogenation of truxene (C27H18) on coinage metal and insulator surfaces. Voltage pulses applied via the…
Synthesis and characterization of super-nonazethrene
Elia Turco, Shantanu Mishra, Jason Melidonie +6
Beginning with the early work of Clar et al. in 1955, zethrenes and their laterally-extended homologues, super-zethrenes, have been intensively studied in the solution phase, and a…
Observation of fractional edge excitations in nanographene spin chains
Shantanu Mishra, Goncalo Catarina, Fupeng Wu +9
Fractionalization is a phenomenon in which strong interactions in a quantum system drive the emergence of excitations with quantum numbers that are absent in the building blocks. O…
Giant magnetic exchange coupling in rhombus-shaped nanographenes with zigzag periphery
Shantanu Mishra, Xuelin Yao, Qiang Chen +11
Nanographenes with zigzag edges are predicted to manifest non-trivial pi-magnetism resulting from the interplay of hybridization of localized frontier states and Coulomb repulsion…
Collective All-Carbon Magnetism in Triangulene Dimers
Shantanu Mishra, Doreen Beyer, Kristjan Eimre +8
Triangular zigzag nanographenes, such as triangulene and its pi-extended homologues, have received widespread attention as organic nanomagnets for molecular spintronics, and may se…
On-surface synthesis of antiaromatic and open-shell indeno[2,1-b]fluorene polymers and their lateral fusion into porous ribbons
Marco Di Giovannantonio, Kristjan Eimre, Aliaksandr V. Yakutovich +8
Polycyclic hydrocarbons have received great attention due to their potential role in organic electronics and, for open-shell systems with unpaired electron densities, in spintronic…
