Abstract X-ray diffraction is a technique used for determining the atomic and molecular structure of a crystal, in which the crystalline atoms cause a beam of incident X-rays to diffract into many specific directions. By measuring the angles and intensities of these diffracted beams, we can produce a three-dimensional picture of the density of electrons within the crystal. From this picture, the mean positions of the atoms in the crystal can be determined, as well as their chemical bonds, their disorder, and various other information. In this seminar we consider crystallography basics, such as difference between crystalline and amorphic materials, their structures, crystal symmetry and unit cell orientation using Miller’s indices. Also we consider two model of X-ray diffraction - Laue's and Bragg’s model. Experimental method and measuring system will be also presented.
