[Wien] bandgap of narrow gap semiconductor (below 1 eV)

[wanxiang feng]

Honorable Professor Blaha,

1. Is that the MBJLDA exchange potential  (PRL, 102, 226401, 2009)
are already implemented in the WIEN2k_09.2 ?  If no, it will be
implemented in the next version? and when the next version will be
released ?

2. Except for MBJLDA, are there some efficient methond to describe
reasonably the bandgap of narrow gap semiconductor (below 1 eV) in
current vesion 09.2 ? Any suggestion will be grateful!


Thanks for your help!

Feng.
