<div dir="ltr"><div>Dear QE users,</div><div><br></div><div>I am new to Quantum espresso. I have a question on building a periodic 2D crystal.
Is it correct to first relax the unit cell and then repeat the unit cell
by using crystal symmetries to build the required crystal (not relaxing
after repetition).</div><div><br></div><div><div>Thank you,</div><div>Ankit Sirohi</div></div></div>
