Layer-thickness effects in quai-two dimensional electron liquids

TL;DR

This paper develops a parameter-free theoretical model to study how layer thickness influences the properties of quasi-two-dimensional electron liquids, aligning well with experimental data.

Contribution

It introduces a CHNC-based approach to accurately compute pair-distribution functions and exchange-correlation energies considering layer thickness effects.

Findings

Good agreement with experimental effective-mass results

Accurate predictions of spin-susceptibility variations

Model free of adjustable parameters

Abstract

We use a mapping of the quasi-2D electron liquid to a classical fluid and use the hypernetted-chain equation inclusive of bridge corrections, i.e., CHNC, to calculate the electron pair-distribution functions and exchange-correlation energies as a function of the density, layer width, spin-polarization and temperature. The theory is free of adjustable parameters and is in good accord with recent effective-mass and spin-susceptibility results for HIGFET 2-D layers.
