Graphene tests of Klein phenomena

TL;DR

This paper explores how graphene's unique electronic properties enable testing Klein phenomena, potentially leading to new insights into barrier interactions and charge accumulation.

Contribution

It introduces the concept of using graphene to test Klein phenomena, highlighting the need to reconsider standard barrier results due to hole accumulation.

Findings

Confirmation of Klein pair production in graphene

Reevaluation of barrier phenomena in the presence of holes

Implications for electronic transport in graphene

Abstract

Graphene is characterized by chiral electronic excitations. As such it provides a perfect testing ground for the production of Klein pairs (electron/holes). If confirmed, the standard results for barrier phenomena must be reconsidered with, as a byproduct, the accumulation within the barrier of holes.
