Van der Waals Frictional Drag induced by Liquid Flow in Low- Dimensional Systems

TL;DR

This paper investigates how liquid flow causes van der Waals frictional drag in low-dimensional systems, revealing that liquid-induced drag can vastly exceed electronic current-induced drag, with implications for nanoscale device design.

Contribution

It provides the first detailed analysis of liquid flow-induced van der Waals friction in 1D and 2D low-dimensional systems, highlighting its potential magnitude.

Findings

Liquid flow-induced friction can be several orders of magnitude larger than electronic current-induced friction.

The study covers both electron systems and channels with liquid in low-dimensional configurations.

Implications for nanoscale device design and fluid-electronic interactions are discussed.

Abstract

We study the van der Waals frictional drag force induced by liquid flow in low-dimensional systems (2D and 1D electron systems, and 2D and 1D channels with liquid). We find that for both 1D and 2D systems, the frictional drag force induced by liquid flow may be several orders of magnitude larger than the frictional drag induced by electronic current.
