Hello everyone,
I would like to ask about an energy dip that occurs while finding the
k-point convergence of TiB2 structure. The output energies are listed
below.
k- points, total energy
5 -206.8480
7 -206.8499
9 -206.8494
11 -206.8494
13 -206.8495
15 -206.8496
As you can see, there is a dip at k=7, although this energy difference
occurs in the 4. decimal place, still looks kind of odd. Have you got
any experience with this phenomenon?
Have a nice day
