How Does Dielectric Confinement Affect Semiconductor Properties?

Click For Summary
SUMMARY

Dielectric confinement significantly alters the dielectric constant (ε) of semiconductors by allowing the electric field to penetrate into a barrier medium with a lower dielectric constant. This effect leads to an effective reduction in the dielectric constant, enhancing semiconductor properties. Key literature includes Keldysh's original paper from 1979, which provides foundational insights into this phenomenon. A valuable presentation on the topic is also available online, offering further clarification and examples.

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.

for further inf.
original paper:
Keldysh, L.V.: Pis’ma Zh. Eksp. Teor. Fiz. 29, 716 (1979). JETPLett. 29, 658, 1979

and very nice prezentation:
