So, if you want to specify a typical circuit, the following might do the work : L-Gamma-X-W-K,U-L-W-X-K,U-Gamma 2¡¢BCC lattice (as for the FCC lattice, there is a scale invariance). Then, the reciprocal primitive vectors (in conventional cartesian coordinates) are (0 1/2 1/2), (1/2 0 1/2), and (1/2 1/2 0) and the coordinates of several special points with respect to primitive vectors in reciprocal space are H (-1/2 1/2 1/2) (conventional cartesian coordinate 1/2 0 0) N ( 0 0 1/2) (conventional cartesian coordinate 1/4 1/4 0) P ( 1/4 1/4 1/4) (conventional cartesian coordinate 1/4 1/4 1/4) So, if you want to specify a typical circuit, the following might do the work : Gamma-H-N-Gamma-P-N-P-H LZ¿ÉÒÔÈ¥ÉÏÊöÍøÖ·Á˽âһϡ£ |
