Cubic systems – unit cellsSimple cubic(sc)Body-centred cubic(bcc)Face-centred cubic(fcc)NB:Only sc is primitive since it contains one lattice pointQ. How many lattice points are contained in a bcc (2) and fcc unit cell? (4)Q. What are basis vectors for each structure?Solid State Physics - Lecture 1
Examples – simple cubic (sc)The simple cubic structure is notcommon in nature.Why?Simple cubicExample – Polonium (alpha form)Q. If the length of one side of theunit cell is 335.2pm. What isdensity of alpha polonium?(9200kg/m 3 )Solid State Physics - Lecture 1
