Title: Out of plane screening and dipolar interaction in heterostructures
Authors: Chan, Cheung
Issue Date: 2009
Abstract: We study the effect of out-of-plane screening (OPS) in an example of heterostructures, symmetric electron-hole bilayer (EHBL). OPS is expected in metal-insulator or metal-semiconductor interfaces while this aspect has been overlooked by previous studies. We consider two types of EHBL systems, which are strongly correlated and as usual electron-hole liquid. The corresponding zero-temperature phase diagrams are obtained with mean field treatment. The modification of plasmon excitations in electron-hole liquid under OPS is also considered. We found that OPS does have effects on properties of layered heterostructures while its effects mainly arise in low density and long wavelength regime.
