1. Application of Euler Angles in Materials Science

3. Orientation contrast image of the surface of a bulk Ga 0.01 In 0.99 As crystal.

4. Crystal structure of Ga 0.01 In 0.99 As is “zincblend”.

5. On page 2 of our article in Physical Review B, we write: “Full crystallographic orientation data of the domains are obtained by Electron BackScattering Diffraction (EBSD). The orientation of a domain is expressed by three Euler angles ,  and  which describe the relationship between sample reference coordinate x, y, and z and crystallographic coordinate a, b, and c. The measured Euler angles demonstrate that the overall disorientations among the domains are small.” X Y sample reference coordinate system a b
