Brillioun zone (BZ) generally refers to a domain in the space of k -vectors, and in that sense are geometric. Band generally refers to energy levels. The concepts are closely related, but they are different, so the glib statement that a BZ is a band is not quite correct, but most people understand what is meant. rayfield dentistry charlotte nc
