Auger Electron Spectroscopy (AES) is a surface-sensitive analytical technique that detects the energy of Auger electrons emitted from a material to determine its elemental composition and chemical state. It is particularly useful for analyzing thin films, surface layers, and interfaces due to its high surface sensitivity and spatial resolution.

Elemental composition refers to the proportion of different chemical elements present in a substance, which determines its physical and chemical properties. Understanding elemental composition is crucial for applications in chemistry, materials science, and environmental studies, as it influences reactivity, stability, and functionality.

Interfaces are crucial in defining the boundaries and interactions between different systems, components, or layers in both software and hardware environments. They enable modularity, interoperability, and abstraction, facilitating communication and integration while maintaining system integrity and flexibility.

Spatial resolution refers to the ability of a sensor or imaging system to distinguish between small details of an object or scene. Higher spatial resolution means finer detail can be observed, which is crucial for applications such as satellite imagery, medical imaging, and digital photography.
