Fabrication and application of arrays related to two-dimensional materials

In recent years, two-dimensional (2D) materials have attracted extensive attention from researchers for their unique structures and electrical properties. 2D materials have been widely applied in field effect transistors, sensors, and photodetectors. Integration is extremely important for practical applications in devices, which requires both minimal crosstalk and high performance. The fabrication of patterned arrays of 2D materials can realize high-density fabrication. In addition, the properties of 2D materials can be also adjusted by the patterned nanostructures. In this review, we summarize the emerging researches related to 2D materials and arrays. Firstly, the preparation strategies of different arrays have been introduced. Then, the applications of arrays have been investigated, such as physical unclonable functions, sensors, energy consumption, photoluminescence enhancement, quantum emitters and photodetectors. Finally, the prospects and existing challenges have been proposed.
