How Does Dielectric Confinement Affect Semiconductor Properties?

[pangru]

What is Dielectric confinement effect?. or could you advise me literature about this?

Thank you.

dielectric constant (ε) of semiconductor can be changed by deposition on high (or low) ε substrate.
==>
Dielectric confinement is effective reduction of the dielectric constant due to the penetration of electric field into barrier medium with a small dielectric constant.
