Electron Energy Loss Spectroscopy (EELS) is a powerful analytical technique used primarily in electron microscopy to study the elemental and electronic properties of materials at the nanoscale. It involves the interaction of high-energy electrons with a specimen. Here’s how it works and its key aspects: ### Principle: 1. **Electron Beam Interaction**: A high-energy electron beam is directed at a thin sample, usually a few nanometers thick, to minimize scattering and ensure that the beam can pass through the specimen.
