Symmetry Analysis of the Structural Space Group D14 Sub 4h

摘要

The crystal system described by the structural space group D(14) sub 4h is considered. The first Brillouin zone for this structure was constructed and analyzed at points of high symmetry. Wave vector groups and character tables for these prints were obtained. The character systems developed may be used for general theoretical band structure calcula tions applied to materials such as stannic oxide and rutile which display this space group. In order to illustrate the results obtained, the symmetry analysis was utilized in the construction of free electron wave functions and energy bands along axes of the zone. (Author)
