Engineering Superfluidity in Electron-Hole Double Layers

TL;DR

This paper investigates the challenges of achieving superfluidity in electron-hole double layers due to band-structure effects and proposes uniaxial pressure as a potential method to realize superfluidity.

Contribution

It identifies band-structure effects as a barrier and suggests uniaxial pressure as a novel approach to induce superfluidity in these systems.

Findings

Band-structure effects likely prevent superfluidity.

Uniaxial pressure may enable superfluidity.

Proposed method opens new experimental possibilities.

Abstract

We show that band-structure effects are likely to prevent superfluidity in semiconductor electron-hole double-layer systems. We suggest the possibility that superfluidity could be realized by the application of uniaxial pressure perpendicular to the electron and hole layers.
