q-points for inelastic transmission spectrum calculation of nanoribbons

[narin]

Hello, I replicated the silicon pn junction inelastic transmission spectrum tutorial. For the silicon structure, following q-points are used in the tutorial:

Code

# Define q-points; take only points in first quadrant in (qx,qy) space
numQx = 7
numQy = 7
dQx = 0.5
dQy = 0.5
qx = numpy.linspace(0,dQx,numQx)
qy = numpy.linspace(0,dQy,numQy)

However I couldn't figure out what Q points to use when I try to find the ITS of nanoribbon structures. Your help would be appreciated. Kindest regards Narin
