Dear Wien2k users,
i am using latest version of wien2k. i want to find out the optical properties. i tested one calculation for Al. i got plasma frequency 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.


i am confused about it that why it gives 0.00 plasma frequency and what means by 0.00 plasma frequency. Please help me to solve this problem. i will be very thankful to you.


Thanks and Regards
Arqum HAshmi
