Electronic and Transport Properties of Graphene Nanoribbons Based on Super-Heptazethrene Molecular Blocks

As these nanoribbons can be assembled according to a broad set of linking hierarchies, as allowed by the geometry of the quantum dot, we investigate the relation between their electronic properties and details of their complex edge structures

Scholarcy highlights

  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • Motivated by the recent synthesis of super-heptazethrene quantum dots, we use theoretical calculations to propose a set of nanoribbons with nontrivial edge structures conceptually based on the fusion of molecular units
  • As these nanoribbons can be assembled according to a broad set of linking hierarchies, as allowed by the geometry of the quantum dot, we investigate the relation between their electronic properties and details of their complex edge structures
  • Since bottom-up routes for the synthesis of carbon nanostructures can be adapted to form intricate junction setups, we investigated the electronic transport properties of S7ZTH-based nanojunctions composed of a central S7ZTH unit at different orientations
  • Our results show that the transmission spectrum is highly sensitive to the junction geometry, and we observe spin-dependent features, which can enable applications in nanoelectronics and spintronics
