texture analysis

**Texture Analysis** in materials science is the **study of the statistical distribution of crystal orientations in a polycrystalline material** — determining whether grains are randomly oriented or show preferential alignment (texture), which strongly influences material properties. **How Is Texture Measured?** - **EBSD**: Measures individual grain orientations -> calculates the Orientation Distribution Function (ODF). - **XRD Pole Figures**: Measures the intensity of specific diffraction peaks as a function of sample orientation. - **Neutron Diffraction**: Bulk texture measurement through the full thickness of thick samples. - **Representation**: Pole figures, inverse pole figures, ODF plots, and misorientation distributions. **Why It Matters** - **Anisotropy**: Texture determines the anisotropy of mechanical, electrical, and magnetic properties. - **Thin Films**: Sputtered and CVD films often develop strong textures that affect subsequent processing. - **Metal Interconnects**: Cu interconnect texture (e.g., (111) vs. (200) preferred orientation) affects electromigration resistance. **Texture Analysis** is **the orientation census of crystals** — measuring whether grains align preferentially and how that alignment affects material behavior.
