<p>The volume of the reciprocal cell is inverse of the unit cell, therefore the number of k points is proportional to the volume... in other words, if the unit cell is increased then the reciprocal cell is reduced and the # of k- points should be reduced proportionally
to give the same k-point density, and thus the same calculation "quality". <br>

<div>Dear users.<br>
<br>
I am trying to calculate band structure of A2 B1-x Cx (x=0, 0.25, 0.5, 0.75) compounds.But for compound x=0.25, 0.5, 0.75 supercell was created. Now can i use different k-points for each of compound. I mean for for x=0.25, 0.5 and 0.75 is it possible to use
less k -points because they takes more time. In other words,can i compare the results of whole compound with each others while their k-points are different.<br>
<br>
thank you.<br>
