<div dir="ltr"><p class="MsoNormal"><span lang="EN-US">Dear all, </span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">I have a simple question about applying the
SCISSORS operation to the density of states (DOS). I have calculated the
density of states for relatively simple Mg-silicates in crystalline phases.
After that I tried to find a way to apply the SCISSORS operation to the
calculated DOS, i.e. a rigid shift of conduction band to a higher energy
region. </span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">I have found that KRAM program can apply
the SCISSORS operation to the conduction band to obtain reliable optical
properties (using OPTIC, JOINT and KRAM). KRAM can generate the case.epsilon, case.sigmak,
case.eloss, and case.sumrules, but it does not seem to be possible to calculate
the DOS with a shifted conduction band according to the arbitrary defined
SCISSORS parameter. However, I cannot find a procedure for applying the
SCISSORS operation to the calculated DOS. </span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">What I want to do is just shift the conduction
band in the calculated DOS to a higher energy region, not calculating optical
properties of the target material. How can I apply the SCSSORS operation on the
calculated DOS using WIEN2k? </span></p>
