Figure 6
(a) Elastic modulus in the directions $[{\bf e}_1^{\,\prime}]$ and $[{\bf e}_2^{\,\prime}]$ . (b) Shear modulus and (c) Poisson's ratio in the directions 12 and 23 for silicon (311). The vector $[{\bf{e}}_1^{\,\prime}]$ is fixed in the normal direction [311], and the vectors $[{\bf e}_2^{\,\prime}]$ and $[{\bf e}_3^{\,\prime}]$ are in the crystal plane (311). The angle α is between the vectors $[{\bf e}_2^{\,\prime}]$ and [0 1 −1]/2^1/2 in the crystal plane: $[{\bf e}_2^{\,\prime}]$ (α=0°) = [0 1 −1]/2^1/2, $[{\bf e}_2^{\,\prime}]$ (α=90°) = [2 −3 −3]/(22)^1/2.
