15/06/2023 @ 17:00 – 18:00 – Ferromagnetism in armchair graphene nanoribbon topological heterostructures George Martins, Physics Institute, Universidade Federal de Uberlândia 15/06/2022 – 5ª. feira –  Sala 776L – 17h   We study the properties of flat-bands that appear in a heterostructure composed of strands of different widths of graphene armchair nanoribbons. One of the flat-bands is reminiscent of the one that appears […]
