Fundamentals of X-Ray Diffraction and Transmission Electron Microscopy

Understanding the internal structure of materials is critical for modern engineering, metallurgy, and nanotechnology. This course provides a clear, comprehensive introduction to the foundational concepts of X-ray Diffraction (XRD) and Transmission Electron Microscopy (TEM) without requiring a complex physics background. You will learn how to interpret diffraction patterns and analyze microstructures to determine crystal systems and identify unknown phases. What you'll learn: - Understand the fundamental physics of X-rays, electron beams, and their interactions with solid matter - Apply Bragg's Law and structure factor calculations to index diffraction peaks - Analyze XRD data to identify crystalline phases and estimate crystallite size - Understand the electron optics, imaging modes, and diffraction mechanisms inside a TEM - Interpret selected area electron diffraction (SAED) patterns for structural analysis - Practice analyzing real-world material characterization scenarios through written case studies Starting with basic crystallography and radiation physics, the curriculum guides you step-by-step through sample preparation principles, instrument geometry, and advanced data interpretation techniques. This text-based course is designed for beginners, engineering students, and entry-level laboratory researchers who want to build a solid theoretical foundation in materials characterization. No prior experience with XRD or TEM is required. Begin your journey into the nanoworld and unlock the secrets of material structures today.
