WebIt is again emphasized that for all cubic lattices the method of Monkhorst and Pack generates not only point sets identical to those obtained by Chadi and Cohen, but also intermediate sets with the same properties. In addition, a comparison of these two methods for the hexagonal lattice reveals our method to be more flexible and efficient. WebThe method of Monkhorst and Pack for special-point generation is explained and an example of its application to the fcc lattice is discussed. Several convergence tests performed with the PWSCF code are presented. The problem of sampling the Fermi surface in metallic systems is briefly discussed.
