<p class=MsoNormal><span lang=EN-US>How about checking partial DOS or fat bands
for the surface atoms. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>You can draw your bulk calculation results
on top of slab calculation results.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>If the thickness of bulk is enough, you can
identify some bands which are similar to bulk one.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>And the variations from bulk can be thought
as surface effects which proceed and dissipate from surface up to some layers into
the center of slab.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Usually for the very surface-wise atom, it
looks quite different from bulk one because of the absence of neighbor.<o:p></o:p></span></p>
