In Frisenda et al., 2020, graphite is mentioned among the naturally occurring van der Waals materials. It was "The exfoliation of two naturally occurring van der Waals minerals, graphite and molybdenite," that "shaped a whole new field of research", that of the 2D materials . In fact, in 2010, the Nobel Prize in Physics was awarded to Andre Geim and Konstantin Novoselov, for experiments regarding the two-dimensional graphene.
