Two-Dimensional Nanostructures for Advanced Applications

Abstract

Two-dimensional (2D) materials have been at the forefront of research for the last decade. Strong quantum confinement, tunable electronic properties, and a large surface area proved to be their best advantage over other nanostructures. The properties like high electron mobility, longer spin lifetime, and excellent mechanical and electrochemical properties make these materials suitable for a wide variety of applications such as photonics, spintronics, energy storage applications, photocatalytic application, thermoelectricity, biomedical applications, and valleytronics. In recent years, significant advancements have been made in these 2D materials, which include graphene and transition metal dichalcogenides such as molybdenum disulfide, tungsten disulfide, hexagonal boron nitride, and phosphorene. In this chapter, we have discussed in a nutshell several important applications of 2D materials that have great value for human beings in the coming years. It is worth emphasizing that advanced applications such as brain-inspired computation, flexible and wearable devices, thermoelectric applications, and photovoltaics based on graphene and molybdenum disulfide have been reviewed thoroughly. Finally, this chapter outlines the future prospective of adapting 2D materials for advanced applications.
