Uncovering the secrets of hidden twists

Twisted layered material junctions,and in particular twisted graphene interfaces,exhibit fascinating physical properties of diverse nature including unique structural,tribological,electronic,as well as heat and electron transport characteristics [1].These properties are intimately related to the moire superstructure formed at the twisted interface,which induces atomic lattice reconstruction patterns that balance between inter-layer registry optimization and intra-layer strain minimization [2].
