Abstract

Graphene is primarily known for its unique electrical and optical properties, emerging in monolayer and bilayer structures. Recently, Bernal stacked multilayer graphene flakes with more than three layers, attracting increasing interest. In contrast to monolayers, multilayer graphene exhibits a much more complex band structure driven by subtle interlayer interactions. These interactions can drive phenomena such as band gap openings and Lifshitz transitions. Here, we investigate the transport properties of a Bernal stacked 14-layer graphene flake, including the influence of strain. Our findings suggest that external strain can effectively tune multilayer graphene through Lifshitz transitions.
