Title: K value in electron phonon coupling analyzer
Post by: ams_nanolab on November 4, 2015, 17:27

In the phonon coupling analyzer, what does k represent? Is it k.point in brillouin zone? What does k=0 signinify?

It is only showing "initial k point index" but it has only one value while k points should be like (a b c). Separately band index for initial and final bands are also given there so this k index can't be band index.

I am really confused.  :o :o :o

Which is why it doesn't say k-point but k-point index. It's an index, 0 means the first point.
