A feasible approach for the assisted self-assembly of twisted layer graphene is described, utilizing a graphene origami-kirigami technique. The process involves controlled induction of wrinkle formation in single-layer graphene, followed by wrinkle folding, tearing, and re-growth. It enables the production of intertwined graphene spirals and conversion of the 1D wrinkles' chiral angle into a 2D twist angle of a 3D superlattice, offering potential for miniaturized electronic components.
A graphene origami-kirigami technique offers an approach for growing intertwined graphene spirals with fixed twist angles, enabling the chirality of one-dimensional wrinkles to be converted into the twist angle of vertically stacked two-dimensional layers. The properties of two-dimensional (2D) van der Waals materials can be tuned through nanostructuring or controlled layer stacking, where interlayer hybridization induces exotic electronic states and transport phenomena. Here we describe a viable approach and underlying mechanism for the assisted self-assembly of twisted layer graphene. The process, which can be implemented in standard chemical vapour deposition growth, is best described by analogy to origami and kirigami with paper. It involves the controlled induction of wrinkle formation in single-layer graphene with subsequent wrinkle folding, tearing and re-growth. Inherent to the process is the formation of intertwined graphene spirals and conversion of the chiral angle of 1D wrinkles into a 2D twist angle of a 3D superlattice. The approach can be extended to other foldable 2D materials and facilitates the production of miniaturized electronic components, including capacitors, resistors, inductors and superconductors.
