Monolayeren

Monolayeren refers to a single layer of atoms or molecules. This ultrathin form of matter possesses unique physical and chemical properties that differ significantly from its bulk counterparts. The behavior of materials at the monolayer scale is dominated by surface effects and quantum mechanical phenomena.

The study of monolayers has gained significant traction with the discovery and development of advanced materials like graphene, a single layer of carbon atoms arranged in a hexagonal lattice. Other examples include hexagonal boron nitride (h-BN), transition metal dichalcogenides (TMDs) such as MoS2, and various organic molecules self-assembled on surfaces.

Fabricating and characterizing monolayers requires specialized techniques. Methods like chemical vapor deposition (CVD), exfoliation (e.g., scotch tape method for graphene), and molecular beam epitaxy (MBE) are employed for their synthesis. Advanced microscopy techniques such as atomic force microscopy (AFM) and scanning tunneling microscopy (STM) are crucial for their visualization and analysis.

The exceptional properties of monolayers, including high electrical conductivity, exceptional mechanical strength, tunable optical absorption, and large surface area to volume ratio, make them promising for a wide range of applications. These include next-generation electronics, sensors, catalysts, energy storage devices, and biocompatible materials. Research continues to explore novel monolayer materials and their potential to revolutionize various technological fields.
