Crystal structure is described in terms of the geometry of arrangement of particles in the unit cells. The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α, β, γ). The position… WebDear students our today's lecture will focus on the crystallographic points directions and planes Essentially we will talk about how to quantitatively describe a crystal structure We will first start from point coordinates how to describe a point position in the crystal structure For example if you have a unit cell characterized by this a, b and c which are unit cell …
