SUMMARY
The Laue method of X-ray Diffraction is a definitive technique for determining the orientation of crystals, as outlined by Ashcroft. This method utilizes diffraction patterns to identify the crystalline axes (a, b, and c) in relation to the sample shape. For instance, in a thin silicon disc (wafer), the Laue method can ascertain which crystal direction, such as 100 or 111, is perpendicular to the wafer's face. This precise orientation determination is crucial for various applications in materials science and engineering.
