Dear Wien2k users,

I have a basic question regarding the analysis
of Density of States. If we find some overlap of DOS of two nearest neighbor
atoms at far below from Fermi energy say at -6 eV can we say that the
orbitals of those two atoms overlap? As the orbitals belongs to the
energy value below the valance bands the states corresponds to the core
states of those individual atoms (they are definitely not the valance
states!!)then how can they overlap?...should we not consider the overlap
as bonding for the states near (valance band) and at Fermi energy?.Any
response in this regard will be very fruitful for us. Thanking you,

with best regards,

[Wien] Fwd: an doubt in the analysis of Density of States

2011-02-05 Thread Gerhard Fecher
I guess no one  understands the question,
a good starter is: Introduction to Solid State Physics by Ch Kittel
