<p>I am trying to do recreate the one dimensional energy bands [fig 1] in the paper "Quantum Spin Hall effect in</p>
<p>Graphene" by C. L. Kane (Ref 1). For it I need to give kpoints path as 0 to pi/a to 2pi/a.</p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">So is this format correct</span></p>
<p><br>

<p>0.0 0.0 0.0 100</p>
<p>1.0 0.0 0.0 100</p>
<p><br>
