ZnSiP has a body centered Bravais lattice and a chalcopyrite structure. See the attach information. Question 1 For the ZnSiP2 material: What is the direction between the 1/4, 1/4, 1/8 P and the 1/2, 1/2, 1/2 Zn? O [-112] [122] O [112] O [223] Question 2 What plane is perpendicular to that direction? (121) O (111) O (-22-3) O (223) Question 3 What is the interplanar spacing of that family of planes? 1.68A O 1.211A O 0.109A O 0.772A Question 4 What is the angle between that plane and (001)?
