Niobium (Nb) has the BCC crystal with a lattice parameter a 0.3294 nm. Find the planar concentrations as the number of atoms per nm2 of the (100), (110) and (111) planes. Which plane has the most concentration of atoms per unit area? Sometimes the number of atoms per unit area nsurface on the surface of a crystal is estimated by using the relation nsurface - nbulk2/3 where nbulk is the concentration of atoms in the bulk. Compare nsurface values with...

Part A The plane famlies When beginning to think sbout calculating the maximum planar density, you will need to consider which plane to use. Selecting a plane can eeem daunting because there are an infinite number of planes in a cubic unit cell. However, when calculating the maximum pianar density for a plane with equal sized atoms, there are only a few families of planes that area important-thosee that pass through the corners of the unit cell. Sort all the...
