Hi,

Think at reciprocal space as a frequencies space. Then the meaning of
the origin of the BZ is obvious. The value of any function there is
just its saptial average.

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.
