and then i find out the inter and intraband contribution. it worked
very well and i got all optical properties. But when i tried to find out
the optical properties of Boron Nitride and Graphene, for both systems
its gives 0.000 plasma frequency and for both systems it gives error
when i include intraband contribution.<br><br>Please guide me, that wien2k optical properties is not fully developed for all type of materials?????? i will be very thankful to you.<br><br>Thanks and Regards<br>Arqum Hashmi<br></div></body></html>
