<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi All<br><br>I have a querry regarding spin orbit coupling. While doing calcualtions with a semiconductor with a heavy element as impurity, is it necessary to do spin-orbit coupling? I am using scalar-relavistic pseudopotential for the impurity element. <br><br>Thanks in advance.<br>Regards<br><br>Padmaja Patnaik<br>
