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

The calculation for pw.x was good but my problem is in finding band
structures.I don't know what k-points is good for this structure.I will
appreciate if tell me what k-point is good for this structure or give me a
recommend that how usually we choose k-point for any structure because I
usually use automatic generation k-point and I don't know how manually i can
choose the k-points.
Sincerely yours
