“…18 For example, graphene changes from linear to parabolic dispersion, 19 and even if we rotate the layers, 20 unexpected phenomena such as superconductivity appear. 21 Two layers of polar materials lead to the appearance of spontaneous ferroelectric properties 22,23 in materials like hexagonal boron nitride 24,25 or TMDs. 26 By stacking two ferromagnetic a Departamento de Física Aplicada I, Escuela Politécnica Superior, Universidad de Sevilla, Seville, E-41011, Spain.…”
