Contains example SCF input files for slabs of Hf, Re, Ta and W (with (001) orientation except for W, which is (110) oriented, for reasons explained in the associated publication. These files enable the user to reproduce the Quantum Espresso calculation of the electronic density of states of these materials (the SCF calculations should be followed by NSCF calculations using the same input parameters and then a PROJWFC calculation, as demonstrated in the QE documentation).
