Dear QE users,
I am a new user of QE. when I went to test the band structure calculation on material ZnO (ibrav=4) with this input file ,I got error band structue (flatt band dispersion).
calculation='bands'
pseudo_dir = '$PSEUDO_DIR/',
outdir='$TMP_DIR/',
prefix='ZnO'
/
&system
ibrav = 4, nbnd =18,
celldm(1) = 6.213,
celldm(3) = 1.610,
nat = 4,
ntyp = 2,
ecutwfc = 40,
ecutrho = 240 ,
occupations ='smearing',
smearing ='methfessel-paxton',
degauss = 0.05,
/
&electrons
mixing_mode = 'plain' ,
mixing_beta = 0.7 ,
diagonalization = 'david' ,
conv_thr = 1.0d-8,
