<div dir="ltr"><div>Dear all, <br></div><div>I will appreciate some clarifications on
the calculation of optical properties of half metal in which the
majority (spin up) channel is semiconducting and metallic in the spin
down channel. After calculating optic -up(-dn) the following steps were
followed. (i) For spin down (metallic) channel: Calculate joint -dn
(with switch 6); Calculate joint -dn (with switch 4)</div><div><b><u>Question</u></b>:How can the intraband and interband contributions be extracted separately for this metallic spin down channel?</div><div>(ii) For the semiconducting spin up channel, switch 4 was used to calculate joint -up.</div><div><u><b>Question</b></u>: Where are the interband contributions written or does the new outcome overwrite the earlier one?</div><div>(iii) joint-updn_lapw <br></div><div><u><b>Question</b></u>:
Is it necessary to use switch 6 in inkram, since we have both
semiconducting and metallic channels mixed in (iii) above? If 1 is used
in line 3 of inkram, shall we regard the outcome of x kram as 'sum' of
both intraband and interband transitions?</div><div><br></div><div>Thanks for your kind assistance.</div><div><br></div><div>Chukwuemeka Okoye</div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div><div><div><i>------------------------------<br>Chukwuemeka M I <b>Okoye</b><br></i></div><i>Department of Physics and Astronomy,<br></i></div><i>University of Nigeria, <br></i></div><i>Nsukka, Enugu State,<br></i></div><i>Nigeria</i><br><div>Telephone: +234 7038766990<br></div><div>E-mail: <a href="mailto:cmi.okoye@unn.edu.ng" target="_blank">cmi.okoye@unn.edu.ng</a><br></div></div></div></div></div></div></div></div></div>
