31. The unit cell of Cd 3 As 2 is tetragonal. 32. The unit cell is rotated by 45?from these squares. 33. The sum is over all atoms in the unit cell . 34. The asymmetric unit refers to the smallest possible occupation of space within the unit cell . 35. Particles in a unit cell become unsymmetrical which allows a net polarisation from each particle. 36. Therefore, a unit cell model is sufficient in representing the microstructure of a UD ply. 37. To further calculate micro stresses at the constituent level, the unit cell model is employed. 38. Next, the pattern is indexed in order to determine the unit cell or lattice parameters. 39. The unit cell contains six crystallographically independent molybdenum sites. 40. The perfect lattice has translation symmetry, which means that all the unit cells are identical.
