Physics has developed a new technology for graphene nanostructures
Due to the unique physical properties, graphene has received more and more attention in recent years. Graphene nanostructures are the basic building blocks of future graphene electronic circuits. A variety of graphene optoelectronics, spintronics, mechanics or biosensing devices are also inseparable from the controllable preparation of graphene nanostructures. At present, the manufacturing methods of graphene nanostructures are mainly divided into two categories: one is bottom-up direct growth or molecular assembly method; the other is top-down processing. Top-down processing is a method for controlling and expanding the preparation of graphene nanostructures in the future, and is currently the focus of research in this field. At present, a variety of methods for processing and tailoring large-area graphene nanostructures from top to bottom have been developed. However, a simple, effective, controllable, batch processable graphene nanostructure patterning technique remains a challenging topic in this research area. The Institute of Physics of the Chinese Academy of Sciences/Beijing National Laboratory for Condensed Matter Physics (Zhang) Research Group has always regarded the study of the controllable processing of graphene nanostructures and their transport properties as an important direction. In the previous research work, they found an intrinsic anisotropic etching effect of graphene [Advanced Materials 22, 4014, (2010)]; based on this, the accuracy of the sawtooth edge graphene nanostructure was realized. Processing and tailoring [Advanced Materials 23, 3061 (2011)]; further studied the electrophonic coupling effect of zigzag edge graphene nanoribbons [Nano letters 11, 4083 (2011)]. Recently, the research team's doctoral student Xie Guibai and others have developed a graphene edge printing technique with a controllable, simple and efficient graphene nanostructure patterning technology. This technique combines the selective deposition of atomic layer deposited oxide on the edge of graphene, and uses the deposited oxide nanobelts as a mask to prepare graphene nanostructures by reactive ion etching. By controlling the size of the nanostructures by atomic layer deposition, the processing of graphene nanostructures with a line width of less than 5 nm can be realized; combined with the anisotropic etching method, a plurality of quasi-one-dimensional graphenes with controllable line widths can be realized. Nanostructures, such as batch processing of nanowires, nanorings, etc. At the same time, this selectively deposited oxide nanoribbon can serve as a dielectric layer for the top gate device, which is another advantage of the graphene edge processing method. Related research papers Graphene Edge Lithography was published in the recent Nano Letters [Nano letters 12, 4642 (2012)]. This work was supported by the National Natural Science Foundation of China, the Ministry of Science and Technology's major research program, and the Chinese Academy of Sciences' “Hundred Talents Programâ€.
