<div dir="ltr"><div>Dear Paolo,</div><div>My question is simple, why the Fermi level is shifted close to valance band or conduction band by shifting the Fermi energy in strained monolayers. <br></div><div>In basic semiconductor, if the Fermi level is close to conduction band then its called n types semiconductor while if the Fermi level is close to the valance band is called p type semiconductor. <br></div><div>In most the software like Wien2k Fermi level is located close to the valance band means all states are filled upto that level and also remain same by applying the strain. but in espresso, its switch to valance band maxima and conduction band minima by according to applied strain. i think, its not acceptable. please correct if i am wrong.</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jul 5, 2018 at 11:47 AM, Rajneesh Chaurasiya <span dir="ltr"><<a href="mailto:rajnano2012@gmail.com" target="_blank">rajnano2012@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Dear All,</div><div><br></div><div>I have computed the electronic band structure under the compression and tensile strain. Change in the conduction band minima and valance band maxima are slightly shifted with strain which i have also verified from the WIEN2K but when i add or subtract the Fermi energy, then i observed in some cases, Fermi level close to conduction and some cases the Fermi energy close to valance band. since by applying the strain the types of semiconductor behavior (n type or p type) does not change. then why the Fermi level is shifted close to valance band maxima or conduction band minima. such types of behavior are not observed in the WIEN2k. why the Fermi level is shifted according to strain? <br></div><span class="HOEnZb"><font color="#888888"><div><br>-- <br><div class="m_8901029262238027299gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr">Thanks & Regards<div>Rajneesh Chaurasiya</div><div>Research Scholar<br></div><div>IIT Jodhpur, India<br></div><div>Mob.
