Disorder engineering and conductivity dome in ReS2 with electrolyte gating

Andras Kis, Oleg Yazyev, Diego José Pasquier, Fernando Gargiulo, Dmitry Ovchinnikov, Adrien Victor Allain, Dumitru Dumcenco

Atomically thin rhenium disulphide (ReS2) is a member of the transition metal dichalcogenide family of materials. This two-dimensional semiconductor is characterized by weak interlayer coupling and a distorted 1T structure, which leads to anisotropy in ele ...

The role of disorder in the electronic and transport properties of monolayer and bilayer graphene

Fernando Gargiulo

This thesis is devoted to the computational study of the electronic and transport properties of monolayer and bilayer graphene in the presence of disorder arising from both topological and point defects. Among the former, we study grain boundaries in monol ...

Controlled growth of a line defect in graphene and implications for gate-tunable valley filtering

Oleg Yazyev, Fernando Gargiulo, Gabriel Albert Autes, Jie Chen

Atomically precise tailoring of graphene can enable unusual transport pathways and new nanometer-scale functional devices. Here we describe a recipe for the controlled production of highly regular "5-5-8" line defects in graphene by means of simultaneous e ...

Grain Boundaries in Graphene on SiC(000(1)over-bar) Substrate

Oleg Yazyev, Fernando Gargiulo

Grain boundaries in epitaxial graphene on the SiC(000 (1) over bar) substrate are studied using scanning tunneling microscopy and spectroscopy. All investigated small-angle grain boundaries show pronounced out-of-plane buckling induced by the strain fields ...

Electronic Transport in Graphene with Aggregated Hydrogen Adatoms

Oleg Yazyev, Fernando Gargiulo, Gabriel Albert Autes, Naunidh Singh Virk

Hydrogen adatoms and other species covalently bound to graphene act as resonant scattering centers affecting the electronic transport properties and inducing Anderson localization. We show that attractive interactions between adatoms on graphene and their ...

Topological Aspects of Charge-Carrier Transmission across Grain Boundaries in Graphene

Oleg Yazyev, Fernando Gargiulo

Dislocations and grain boundaries are intrinsic topological defects of large-scale polycrystalline samples of graphene. These structural irregularities have been shown to strongly affect electronic transport in this material. Here, we report a systematic i ...
