Title: Understanding the non-covalent interaction mediated modulations to the electronic structure of quasi-zero-dimensional graphene nanoflakes
Biography: Amrit Sarmah
In the contemporary years, the magnetic or electric field induced modulations to the electronic environment of single molecular systems are a common practice. In this particular study, we have instigated the possibility of controlling the electronic and spin-dependent properties of hydrogen-terminated graphene fragments, so-called graphene nanoflakes (GNF) using weak noncovalent interaction as the external stimuli. The topological frustration in the graphene fragment appreciated the compelling electronic behavior of the system. This leads to some unorthodox spin-distribution in the system and it is possible to synchronize this electronic perturbation switching through a non-covalent interaction. These findings institute new avenue to sculpting such donor-acceptor composite as a self-regulated spintronic device in the next generation electronics.
