| 41. | There are 12 tetrahedra in the A-centered unit cell.
|
| 42. | Properties such as the phase transition temperature and unit cell sizes vary smoothly with the composition.
|
| 43. | Hence given a suitable initial polygon inscribed in a unit cell periodic surfaces can be constructed.
|
| 44. | There are four atoms in each unit cell.
|
| 45. | There are two crystallographically distinct Si atoms and five different oxygen positions in the unit cell.
|
| 46. | In this case there are sixteen small cages and eight large ones in the unit cell.
|
| 47. | The unit cell dimension is 4.01 ?
|
| 48. | The characteristic rotation and mirror symmetries of the unit cell is described by its crystallographic point group.
|
| 49. | Consider an FCC compound unit cell.
|
| 50. | For example, optical and unit cells.
