Atomréteget

Atomréteget is a term of Hungarian origin that translates to "atomic layer" or "atomic thickness." It refers to a material or a film that is composed of a single or a very small number of atomic layers. This concept is crucial in fields such as nanotechnology, materials science, and semiconductor manufacturing where precise control over material thickness at the atomic scale is required.

The fabrication of atomréteget films is often achieved through techniques like Atomic Layer Deposition (ALD) or Atomic Layer Etching (ALE). ALD, for instance, is a chemical vapor deposition method that deposits material one atomic layer at a time through sequential, self-limiting surface reactions. This process allows for highly conformal coating and extremely precise thickness control, making it ideal for creating ultrathin films with specific electronic, optical, or mechanical properties.

Atomréteget materials, such as graphene, transition metal dichalcogenides (TMDs), and ultrathin oxides, exhibit unique physical and chemical properties that differ significantly from their bulk counterparts. These properties arise from quantum mechanical effects and the high surface-to-volume ratio inherent in such thin materials. Their applications are diverse, ranging from advanced electronics and sensors to catalysis and energy storage devices. The study and manipulation of atomréteget represent a frontier in scientific research and technological innovation.
