Control of electron trapping effects in graphene quantum dots via light polarization state

TL;DR

This paper theoretically investigates how the polarization state of external light influences electron trapping in graphene quantum dots, revealing that specific polarizations induce scattering resonances and electron trapping effects.

Contribution

It introduces a theoretical framework showing how light polarization can control electron trapping in graphene quantum dots, a novel approach for quantum device manipulation.

Findings

Certain light polarization states induce scattering resonances.

Electron trapping effects can be controlled via light polarization.

Resonance conditions depend on the polarization parameters.

Abstract

We theoretically analyze the scattering process of an electron on a graphene quantum dot (GQD) exposed to an external light irradiation. We prove that for suitable choices of the light polarization state, there emerge scattering resonances, characterized by electron trapping effects inside the GQD.
