Dear All,
I find a question about the irreducible Brillouin zone of a
triangular lattice in MPB.
In the MPB manual, it give a example for the irreducible
Brillouin zone of a triangular lattice :
set! k-points (list (vector3 0 0 0) ; Gamma
(vector3 0 0.5 0) ; M
(vector3 (/ -3) (/ 3) 0) ; K
(vector3 0 0 0))) ; Gamma
(set! k-points (interpolate 4 k-points))
I am confused at the value of K point!
I think the value of K point should be (vector3 (/ 0.5 sqrt(3))
0.50).please see the picture attached.
Why Steven put (vector3 (/ -3) (/ 3) 0) here?
0, 0.5
0.5/sqrt3, 0.5
Gamma
0, 0
M
K
