The Development of High-Temperature Superconductors and 2D Iron-Based Superconductors

2D materials have attracted extensive interest due to its excellent properties such as high mobility, high conductivity and high mechanical strength and long spin diffusion length for spintronics devices. Many researches have focused on the 2D materials with pure form. However, doping in 2D materials have been paid more and more attention because novel properties can be achieved by doping, such as possessing both semiconductor and spin behavior, achieving high sensitivity as well as high power harvest efficiency. In this chapter, we will discuss the preparation method for 2D materials doping, theoretical modeling, the properties achieved by doping and their applications.
