[Pw_forum] Bands

[Lars Matthes]

Dear Winfred Mulwa,

first, your bands are correctly extracted from the output of Espresso,
although some very low lying bands are missing. The bands show almost no
dispersion, I can just guess, but your lattice constant might be too big
which results in weakly interacting (almost isolated) atoms and therefore
discrete energy levels instead of bands.
...Just an idea.

Regards
Lars
