Two-dimensional (2D) materials have revolutionized the field of electronics and photonics with their unique properties. These materials are only a few atoms thick, offering exceptional electrical, optical, and mechanical characteristics that are not found in bulk materials.
Introduction to 2D Materials
2D materials, such as graphene, transition metal dichalcogenides (TMDs), and hexagonal boron nitride, have garnered significant interest due to their remarkable properties. Graphene, the most famous 2D material, is known for its high electrical conductivity, strength, and flexibility.
Applications in Electronics
In electronics, 2D materials enable the development of faster, smaller, and more energy-efficient devices. Their atomic thinness allows for the creation of ultra-scaled transistors and flexible electronic components. For example, TMDs like MoS2 are used to make high-performance field-effect transistors (FETs) with excellent on/off ratios.
