Dear community. As far as I understand, the dielectric confinement problem is scale invariant, while the quantum confinement problem has a length scale defined by the Bohr radius.

I have been trying to understand some experimental results in terms of the change in dielectric confinement of the system: one material phase, with a higher permittivity, embedded into a secondary phase with a lower permittivity. After some treatment, the phases distribution change, with the first phase increasing its volume ratio. This will be consistent with changes in dielectric confinement. The problem is that the scale of the phases is way above the Bohr radius of the specific material, and all the literature I have found, deals with dielectric confinement only for very confined systems, within the quantum confined scale.

Can anyone point me to some literature that deals with the scale of dielectric confinement?

Thanks.
