Metals with fcc structure

WebThe simplest unit cell is Simple Cubic (SC). This crystal structure is just a cube with an atom on each corner. The simple cubic unit cell may also be called “primitive cubic” and thus abbreviated as cP. The simple cubic unit cell belongs to space group #221 or , Strukturbericht A h, and Pearson symbol cP1. αPo is the prototype for SC. WebExamples of fcc include aluminium, copper, gold and silver. Another important cubic crystal structure is the diamond cubic structure, which can appear in carbon, silicon, …
