In three dimensions the point symmetry groups require 14 fundamental types of lattices. |
|
Among these types, the students of this course explore briefly a few simple crystal structures of |
|
general interest. Then they understand the index system for crystal structures in order to |
|
specify a crystal plane. |

|
The students of this course examines the Bragg law, which tells us that the diffracted beams are |
|
found when θ and λ are matched. |
|
Further they are to analyze X-ray diffraction by means of the reciprocal lattice vectors and the |
|
Brillouin zone as a Wigner-Seitz cell in the reciprocal lattice. |
