Crystallographic vector

Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (krystallos) "clear ice, rock-crystal", with its meaning extending to all solids with some deg… WebA primitive cell is a unit cell built on the basis vectors of a primitive basis of the direct lattice, namely a crystallographic basis of the vector lattice L such that every lattice vector t of L may be obtained as an integral linear combination of the basis vectors, a, b, c.

WebA crystallographic defect is an interruption of the regular patterns of arrangement of atoms or molecules in crystalline solids.The positions and orientations of particles, which are repeating at fixed distances determined by the unit cell parameters in crystals, exhibit a periodic crystal structure, but this is usually imperfect. Several types of defects are often … WebIn crystallography, we use the Z-axis much more than in high school math. A clearer way to draw these axes is to have the X axis travel towards you (down and left), the Y axis travel to the right, and the Z-axis travel upwards.
