Discovery of new growth-directed graphene stacking domains may precede new era for quantum applications

Researchers from New York University and Charles University in Prague, Czech Republic, have observed growth-induced self-organized stacking domains when three graphene layers are stacked and twisted with precision. The findings demonstrate how specific stacking arrangements in three-layer graphene systems emerge naturally – eliminating the need for complex, non-scalable techniques traditionally used in graphene twisting fabrication. The size and shape of these stacking domains are influenced by the interplay of strain and the geometry of the three-layer graphene regions. Some domains form as stripe-like structures, tens of nanometers wide and extending over microns.
