What Are 2D Materials? 

Two-dimensional (2D) materials consist of extremely thin layers that extend in two dimensions with almost no thickness in the third dimension. These materials possess unique and distinct properties due to their ultra-thin structure, which can be just a few atoms thick at the atomic or molecular level. With a flat surface at the atomic scale, these materials exhibit differences in electronic, optical, and mechanical properties compared to traditional materials.

The most well-known example of 2D materials is graphene. Graphene has a two-dimensional structure where carbon atoms are arranged in a honeycomb pattern. It is renowned for its exceptional electrical conductivity, high mechanical strength, and unique thermal properties. The discovery and development of graphene have encouraged scientists to explore and research other 2D materials. Materials such as phosphorene, molybdenum disulfide (MoS2), and hexagonal boron nitride (h-BN) also display similar ultra-thin structures, offering potential for use in electronics, photovoltaic applications, and sensors, among many other areas.

How 2D Materials Are Synthesized?

At its core, the synthesis of 2D materials involves the delicate orchestration of atoms into layers just one atom thick, manifesting unique properties that are not found in their bulk counterparts. The traditional workhorse for this task has been the CVD technique. CVD operates on the principle of depositing gaseous reactants onto a substrate, where they undergo a series of chemical reactions to form a solid material. The process demands meticulous control over numerous parameters: temperature must be finely tuned to facilitate the desired reactions; pressure must be carefully managed to ensure the correct gas phase conditions; and the chemical precursors must be precisely balanced to yield the targeted material.

However, these requirements underscore the primary challenges in 2D material synthesis: consistency and scalability. Achieving uniformity across a substrate is notoriously difficult, with slight variations in conditions leading to significant discrepancies in material quality. Moreover, scaling up this process while maintaining high quality remains a daunting task, limiting the practical applications of 2D materials.
