Dear all,<br> I have calculated the rhombohedral cell with R space group using hexagonal lattice parameters.I think the struct is well. And the scf is also nothing wrong. But when I selected the k-point to calculate the band structure,I found the primitive Brillouin-zone was very strange that is different from normal BZ of hexagonal cell. The three axises don't perpendicular with each other. And I can't find the special k-points I want to get. I don't know what's wrong with it. How should I go on with the calculation of band .<br> Any comments will be appreciated. Thank you in
advance.<br><br> Mary<br><p>
