Applications of focused laser beams in micro-nano materials

Low-dimensional micro-nano materials will play an important role in electronic and optoelectronic devices in the post-Moore law period because of their unique small size effects and their resulting interesting physical properties. Due to the small size characteristics of micronano materials, it is difficult to achieve precise control using traditional techniques. This restricts the application of micro-nano materials in miniaturized, integrated and diversified devices. This article presents a review on the development of focused laser beam technology, especially on how it can be used to achieve the precise manipulation, manufacture and modification of micro-nano materials. Finally, we look at the future prospects of focused laser beam technology.
