<div dir="ltr">Dear users,<div><br></div><div>Hello,</div><div><br></div><div>I have faced with a problem which though it is simple, I can not do it. </div><div>Actually, I want to plot data of density of states with reference to vacuum level (E_vac).</div><div>As it is well understood, the produced data are with reference to average electrostatic potential (E_aep).</div><div>However, I have calculated the vacuum level (E_vac) using work function calculations.</div><div>I was wondering if that is correct to obtain the data with reference to vacuum level by shifting the data by E_vac value. I mean that the desired value will be obtained by subtracting the E_vac from E_aep, setting the vacuum level as zero energy level. Is it true? </div><div>Any comment will be appreciated.</div><div>Thanks in advance.</div><div><br></div><div>Regards,</div><div>Mohaddeseh</div><div><br></div><div>Is it correct to just shift data </div><div><div><br></div>-- <br><div class="gmail-m_-1413416847524900871gmail_signature">------------------------------<wbr>---------------------------<br><br>Mohaddeseh Abbasnejad, <br>Assistant Professor of Physics,<br>Faculty of Physics,<br>Shahid Bahonar University of Kerman,<br>Kerman, Iran<br>P.O.
