Hey guys,
I just realized that there is a gap somewhere in my understanding of K vectors and reciprocal space.
My question is how can we talk about K vectors "living" in the first Brillouin Zone, when these vectors cannot be expressed on the vector form of reciprocal space ( r*=ha*kb*+lc* , where h,k,l integers)? First Brillouin Zone as I understand it, extends until half the length of the first neighboring lattice point of the reciprocal space.
