Abstract
Abstract: Graphene is an atomic-thickness carbon lattice that can be exfoliated from solid graphite or grown using high temperature processing methods on a variety of substrates. Many practical applications of large-area graphene, however, are limited by the transport mobility and carrier concentration homogeneity over distances greater than hundreds of microns. This presentation reports on the characteristics of large area (25 mm2) monolayer devices that display precise quantum Hall effect (QHE) characteristics at reasonable cryogenic temperatures, surpassing the previously reported records for graphene.
