Engineering high disorder-resistant and large positive magneto-transport intrinsically in radial superlattice

Carbon nanoscrolls (CNSs), obtained by rolling up ultra-thin graphene nanosheets into spiral-like tubular structures, are radial superlattices with two open endpoints and one closed-interfaced domain-walled structure. The heterostructurally domain-walled CNSs especially possess topological electronic states. However, little is known about the intrinsic mechanism. By combining the continuum model, the tight-binding method, and the density functional theory calculations to investigate the magneto-electronic states, we prove that the tunable interlayer tunneling, which is affected by van der Waals interaction and electron-orbital configurations, and the domain-walled interface boundary conditions result in the coexistence of nanoribbons and nanotubes in CNSs. Furthermore, we demonstrate that CNSs are characterized not only by a large positive magnetoconductance of up to 200%, compared to carbon nanoribbons, but also by a high on-site disorder-resistant magnetoconductance plateau. This work highlights the key factors in modulating the carrier magneto-transport of CNSs, which offers crucial hints to synthesizing and designing heterostructure-interfaced radial complex oxide superlattices in the high-performance curved nanomembrane material realm.
