<p>Dear Users and Developers,</p>
<p>I am studying the electronic structure of a surface covered by a heavy metal overlayer. I have reasons to think that the interaction between the two elements enhances the spin-orbit splitting of a particular surface state. I would like to understand which is the dominating effect in such an enhancement : is it mainly due to symmetry changes induced by the overlayer or to the spin-orbit carried by the overlayer's atoms?</p>
<p>To this aim, I'm planning to run a simulation with a full-relativistic pseudopotential for the substrate element, and a scalar-relativistic one for the overlayer atoms. My questions are (1) Is that a safe procedure, i.e. does QE handle such a mixed kind of simulation? (2) Is there any other delicate aspects I should be aware of when carrying out a simulation like this?</p>
<p>Many thanks in advance. Cheers </p>
