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…
Coupled spin states in armchair graphene nanoribbons with asymmetric zigzag edge extensions
Qiang Sun, Xuelin Yao, Oliver Groning +6
Carbon-based magnetic structures promise significantly longer coherence times than traditional magnetic materials, which is of fundamental importance for spintronic applications. A…
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…
Ab Initio calculation of field emission from metal surfaces with atomic--scale defects
Heikki Toijala, Kristjan Eimre, Andreas Kyritsakis +2
In this work we combine density functional theory and quantum transport calculations to study the influence of atomic--scale defects on the work function and field emission charact…
