Inquiry about transiesta
Dear friends,
I have observed some odd behaviors of TranSiesta. The attach plot is
the plot of the planar charge density of along the z-direction
of Graphene-BN-Graphene stacks. The stack is in the z-direction.
The basis is double-zeta types for both grapheme and BN.
As you can see, there is no charge at all in the BN layers, which is odd.
I observed the same behaviors in other systems when using BasisSizes=DZP.
However, when I changed to BasisSizes=SZP, the charge density reappeared.
If you could kindly provide some insights into this issue, I would be greatly appreciated.
The basis block is also below. I have optimized the basis using the simplex algorithm.
The resultant lattice parameters look fine.
Sincerely,
Yuranan
