Dear users<br>I want to simulate a nanostructure with using espresso code so I give this structure <br><br>&CONTROL<br> calculation = 'nscf' ,<br> restart_mode = 'from_scratch' , <br> outdir = '/home/zareh/espresso-
2.1.3/work/zns_nano/' ,<br> pseudo_dir = '/home/zareh/espresso-2.1.3/pseudo/' ,<br> prefix = zns ,<br> etot_conv_thr = 1.D-6 ,<br> forc_conv_thr = 1.D-5 ,<br>
/<br> &SYSTEM<br> ibrav = 2,<br> celldm(1) = 30.670266,<br> nat = 10,<br> ntyp = 2, <br> ecutwfc = 20. ,<br> nosym = .true. ,
<br> occupations = 'smearing' ,<br> degauss = 0.002 ,<br> nspin = 1 ,<br> /<br> &ELECTRONS<br> diagonalization = 'cg' ,<br> /<br>ATOMIC_SPECIES<br>
