Prediction of Giant Electro-actuation for Carbon Nanoscrolls

TL;DR

This paper investigates the electro-mechanical behavior of carbon nanoscrolls, revealing their potential as highly efficient nano-actuators due to their large radial response upon charge injection.

Contribution

It provides first-principles analysis showing carbon nanoscrolls have significantly larger radial electro-mechanical responses than nanotubes, highlighting their suitability for nano-actuator applications.

Findings

Radial response upon charge injection is up to ten times larger than in nanotubes.

Carbon nanoscrolls exhibit high stability and sensitivity similar to nanotubes.

Potential for developing highly efficient nano-actuators.

Abstract

We study by first-principles calculations the electro-mechanical response of carbon nanoscrolls. We show that although they present a very similar behavior to carbon nanotubes for what concerns the axial deformation sensitivity, they exhibit a radial response upon charge injection which is up to one order of magnitude larger. In association with their high stability, this behavior make them a natural choice for a new class of very efficient nano-actuators.
