Topological phases and twisting of graphene on a dichalcogenide monolayer
Abdulrhman M. Alsharari, Mahmoud M. Asmar, Sergio E. Ulloa
Depositing monolayer graphene on a transition metal dichalcogenide (TMD) semiconductor substrate has been shown to change the dynamics of the electronic states in graphene, inducin…
Lateral Interfaces of Transition Metal Dichalcogenides: A Stable Tunable One-Dimensional Physics Platform
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study in-plane lateral heterostructures of commensurate transition-metal dichalcogenides, such as MoS-WS and MoSe-WSe, and find interfacial and edge stat…
Sublattice symmetry breaking and Kondo-effect enhancement in strained graphene
Dawei Zhai, Kevin Ingersent, Sergio E. Ulloa +1
Kondo physics in doped monolayer graphene is predicted to exhibit unusual features due to the linear vanishing of the pristine material's density of states at the Dirac point. Desp…
Local versus extended deformed graphene geometries for valley filtering
Dawei Zhai, Nancy Sandler
The existence of two-inequivalent valleys in the band structure of graphene has motivated the search of mechanisms that allow their separation and control for potential device appl…
Tunable spin-polarized edge currents in proximitized transition metal dichalcogenides
Natalia Cortés, O. Ávalos-Ovando, L. Rosales +2
We explore proximity-induced ferromagnetism on transition metal dichalcogenide (TMD), focusing on molybdenum ditelluride (MoTe) ribbons with zigzag edges, deposited on ferrom…
Electron Scattering in 2D Semiconductors: Contrasting Dirac and Schrödinger Behavior
D. Meneses-Gustin, S. E. Ulloa, V. Lopez-Richard
Electronic transport through a material depends on the response to local perturbations induced by defects or impurities in the material. The scattering processes can be described i…
Quantum Wires and Waveguides Formed in Graphene by Strain
Y. Wu, D. Zhai, C. Pan +5
Confinement of electrons in graphene to make devices has proven to be a challenging task. Electrostatic methods fail because of Klein tunneling, while etching into nanoribbons requ…
Proximity-induced topological phases in bilayer graphene
Abdulrhman M. Alsharari, Mahmoud M. Asmar, Sergio E. Ulloa
We study the band structure of phases induced by depositing bilayer graphene on a transition metal dichalcogenide monolayer. Tight-binding and low-energy effective Hamiltonian calc…
