Hi all,

I can understand the concept of the first Brillouin Zone, but I cann't 
figure out the meaning of the origin of the first BZ and which planes 
are corresponding to it in the real lattice space.  I mean, the origin 
coordinate of the first Brillouin Zone is (0, 0, 0), so the 
corresponding plane(s) to it in the real lattice space should have the 
index (/infty /infty /infty ).  But what does this plane index mean, I 
just cann't understand.  Would anyone give me some hints on this?

Thanks in advance.
