Self-assembly pre-occupancy for 2D super-ordered emptiness arrays in graphene

Self-assembly is deemed to be an effective and inspiring strategy construct programmable innovative super-ordered structures. Here, we have, for the first time, achieved large-area two-dimensional (2D) emptiness arrays in graphene by silicon dioxide self-assembly pre-occupancy. The prominent uniform periodicity of 2D can flexibly adjusted. synergistic interaction between pre-occupancy structural unit contributes successful acquisition arrays. realization would shed light on rational redaction, fabrication research complex structure systems facilitate their applications various fields, such as highly integrated functional devices, precise location systems, sensing, separation, so on.
