Strain Solitons and Topological Defects in Bilayer Graphene

Jonathan S. Aldena, Adam W. Tsena, Pinshane Y. Huanga, Robert Hovdena, Lola Brownb, Jiwoong Parkb,c, David A. Mullera,c, and Paul L. McEuen; Cornell University

Bilayer graphene has been a subject of intense study in recent years. The interlayer registry between the layers can have dramatic effects on the electronic properties: for example, in the presence of a perpendicular electric field, a band gap appears in the electronic spectrum of so-called Bernal-stacked graphene. This band gap is intimately tied to a structural spontaneous symmetry breaking in bilayer graphene, where one of the graphene layers shifts by an atomic spacing with respect to the other. This shift can happen in multiple directions, resulting in multiple stacking domains with soliton-like structural boundaries between them...
