<div dir="ltr">Dear QE users,<div><br></div><div>I am trying to calculate DOS of 25% Nd-doped LaPO4 bulk. LaPO4 has four La per unit cell, so I am replacing one La by Nd in each unit cell. I am using 1x1x1 cell for this doping. I am not sure if image charge interaction has to be considered for such calculation. Do wo have to consider image charge interaction in such a calculation of doped bulk sample? I have given a part of input file for SCF calculation.</div><div><br></div><div><br></div><div><pre style="color:rgb(0,0,0);white-space:pre-wrap"> &SYSTEM
