Dear QE users
I am new at QE. Can you please give me an idea about DFT-D3 calculation?
Thank you in advance.
Regards
Hemant

Hello Everyone, Good Afternoon,
I want to calculate vdw potential seen by electrons in monolayer 1 tmdc
due to charge density on the 2nd layer and vice versa. For this
non-local-correlation contribution to the potential points on the grid on
the surface is needed. I check in the Quantum espresso VDW-D3 directory
there and I see only the improvement in energy not potential due to vdw
interaction. Could you help me to calculate the vdw potential and related
subroutine. Looking forward to your help. Thank you!
