In the first chapter, students learn how crystals are systematised, e.g., the point symmetry |
|
groups in three dimensions require 14 fundamental types of lattices. Among these types, the |
|
students 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. |

2. Crystal Diffraction and the Reciprocal Lattice |
15 |
(1) Diffraction of Waves by Crystals |
|
(2) Scattered Wave Amplitude |
|
(3) Brillouin Zone |
|
(4) Fourier Analysis of the Basis |
|
|
|
In the second chapter, the students learn the Bragg law, which tells us that the diffracted beams |
|
are found when θ and λ satisfy specific conditions. Further, they understand X-ray diffraction |
|
by means of the reciprocal lattice vectors and the Brillouin zone. |
