Reset and switch protocols at Landauer limit in a graphene buckled ribbon

TL;DR

This study uses molecular dynamics simulations to demonstrate that a graphene buckled ribbon can operate as a nano electromechanical switch at the Landauer limit, minimizing heat dissipation during reset and switch operations.

Contribution

It introduces a novel graphene-based nano switch that approaches the thermodynamic limit of heat dissipation, advancing low-power nanoelectromechanical device design.

Findings

Reset and switch protocols operate near the Landauer limit

Graphene buckled ribbon functions effectively as a nano switch

Heat dissipation approaches fundamental thermodynamic bounds

Abstract

Heat produced during a reset operation is meant to show a fundamental bound known as Landauer limit, while simple switch operations have an expected minimum amount of produced heat equal to zero. However, in both cases, present-day technology realizations dissipate far beyond these theoretical limits. In this paper we present a study based on molecular dynamics simulations, where reset and switch protocols are applied on a graphene buckled ribbon, employed here as a nano electromechanical switch working at the thermodynamic limit.
