Electronic fibre in graphene

TL;DR

This paper theoretically explores how a p-n-p junction in graphene can act as an electronic fiber, enabling dissipationless electron propagation due to the analogy with light propagation in Maxwell's equations.

Contribution

It introduces the concept of a graphene-based electronic fiber using the analogy between Dirac fermions and photons, showing potential for dissipationless transport.

Findings

p-n-p junction acts as an electronic fiber

Electrons propagate without dissipation in the channel

Transport properties resemble light propagation in Maxwell's equations

Abstract

We investigate theoretically the transmission properties through a p-n-p junction on graphene. Here we show that the electronic transport property presents deep analogies with light propagation. It originates from the similarity between the linear spectrum of the Dirac fermions and photons that obey the Maxwell's equations. We demonstrate the p-n-p channel acts as a electronic fiber in which electrons propagate along the channel without dissipation.
