Lateral heterostructures and one-dimensional interfaces in 2D transition metal dichalcogenides
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
The growth and exfoliation of two-dimensional (2D) materials have led to the creation of edges and novel interfacial states at the juncture between crystals with different composit…
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…
Symmetries and hybridization in the indirect interaction between magnetic moments in MoS nanoflakes
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida interaction between magnetic impurities embedded in -doped transition metal dichalcogenide triangular flakes. The role of underlying s…
Long range of indirect exchange interaction on the edges of MoS flakes
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida interaction between two magnetic impurities connected to the edges of zigzag-terminated MoS flakes. When the impurities lie on the…
Noncollinear exchange interaction in transition metal dichalcogenide edges
Oscar Ávalos-Ovando, Diego Mastrogiuseppe, Sergio E. Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida effective exchange interaction between magnetic impurities embedded on the edges of transition-metal dichalcogenide flakes, using a three…
Hybridization and anisotropy in the exchange interaction in 3D Dirac semimetals
Diego Mastrogiuseppe, Nancy Sandler, Sergio Ulloa
We study the Ruderman-Kittel-Kasuya-Yosida interaction in 3D Dirac semimetals. Using retarded Green's functions in real space, we obtain and analyze asymptotic expressions for the…
