Surface analysis is a set of techniques used to study the physical and chemical properties of a material's surface. This analysis helps scientists understand how materials interact with their environment, which is crucial in fields like materials science, nanotechnology, and semiconductor manufacturing. Common methods of surface analysis include X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). These techniques provide detailed information about surface composition, structure, and morphology, allowing researchers to optimize materials for various applications, such as coatings, catalysts, and electronic devices.
