Hi,

To calculate dielectric constant, do we have to terminate dangling-bond (if it exits) with H?

Best regards,

Not necessarily, but if you want the static dielectric tensor (from linear response in the phonon code) you absolutely need an insulator. If your system s metallic, you can still compute the complex dielectric tensor with the epsilon.x code. I don't know if what you compute would make sense physically, it depends on the details.
