Unformatted text preview: = (2 )/6 and thus /2 = /6. As seen in the gure above, the location that was found from Buergers construction, location 4, is the location of a 6fold symmetry axis, and this location is already a lattice point. A 6fold axis of rotation inherently has 3 and 2fold symmetry. Using Buergers construction we can nd the location of the 3fold symmetry axis. This is displayed below. For 3fold symmetry = (2 )/3 and thus /2 = /3. 4 As mentioned above, 6fold symmetry has 2fold symmetry as well. The location of the 2fold axis was found using Buergers construction; see the gure below. For 2fold symmetry = (2 )/2 and thus /2 = /2. Using the information obtained throughout this process, one can display all the symmetry operations on a primitive unit cell for a lattice that has perpendicular 6fold axis symmetry and translational symmetry. 5...
