Spin and electronic excitations in atomic chains on Au(111) substrates
David W. Facemyer, Naveen K. Dandu, Alex Taekyung Lee +3
High spin systems, like those that incorporate rare-earth elements (REEs), are increasingly relevant in many fields. Although research in such systems is sparse, the large Hil…
Entropy and Seebeck signals meet on the edges
Natalia Cortés, Patricio Vargas, S. E. Ulloa
We explore the electronic entropy per particle and Seebeck coefficient in zigzag graphene ribbons. Pristine and edge-doped ribbons are considered using tight-bind…
Inducing chiral superconductivity on honeycomb lattice systems
Abdulrhman M. Alsharari, Sergio E. Ulloa
Superconductivity in graphene-based systems has recently attracted much attention, as either intrinsic behavior or induced by proximity to a superconductor may lead to interesting…
Reversible edge spin currents in antiferromagnetically proximitized dichalcogenides
Natalia Cortés, O. Ávalos-Ovando, S. E. Ulloa
We explore proximity effects on transition metal dichalcogenide ribbons deposited on antiferromagnetic (AFM) insulating substrates. We model these hybrid heterostructures using a t…
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…
