Surface Morphology

Definition

Surface morphology refers to the study and characterization of the surface features and structures of materials at various scales. It encompasses aspects such as texture, roughness, and the arrangement of surface atoms, which can significantly influence the physical and chemical properties of materials, particularly when they interact with plasma. Understanding surface morphology is crucial in both modeling plasma-surface interactions and in characterizing nanomaterials synthesized through plasma processes.
