1. Unit cell and Crystal A unit cell is defined as the basic structural part in the composition of materials. It is analogous to a brick used in the building construction. When many unit cells repeat in a three-dimensional space, Read more…
The study of geometry and structure of solids is a science known as crystallography. X-rays and microscopes have substantially contributed to this area. The atoms and molecules are held together by chemical bonds in the solids. The orientation, periodicity, and Read more…
