(a) Elastic modulus in the directions and . (b) Shear modulus and (c) Poisson's ratio in the directions 12 and 23 for silicon (110). The vector is fixed in the normal direction [110], and the vectors and are in the crystal plane (110). The angle α is between the vectors and [0 0 1] in the crystal plane: (α = 0°) = [0 0 1], (α = 90°) = [1 −1 0]/21/2. |
