Project description
Topological structures based on chalcogenide superlattices
Funded by the Marie Skłodowska-Curie Actions programme, the MagTopCSL project aims to investigate superlattices and heterostructures in chalcogenide materials to be used as platforms in topological devices. To this end, superlattices created by superimposing single and double layers of transition-metal dichalcogenides with periodic arrays of magnetic adatoms in various configurations will be studied. Moreover, the project will investigate multilayer heterostructures of group-II monochalcogenides. The interplay of the underlying electronic structures with the superstructure ingredients and configurations could lead to new Hall phases with highly altered properties.
Objective
I will explore superlattices and heterostructures in chalcogenide materials as a platform for Berry-curvature engineering and topological devices. To this end, I will study superlattices created by superimposing single- and bilayers of transition-metal dichalcogenides with periodic arrays of magnetic adatoms in various configurations. Moreover, I will study multilayer heterostructures of group-II monochalcogenides with a compositional gradient across layers. The interplay of the underlying electronic structures with the ingredients and configurations of the superstructures is envisioned to lead to new phases with highly altered properties. I will study this interplay theoretically with a focus on three main objectives: (i) designing quantum anomalous Hall phases with large Chern numbers, which is highly relevant for electronic devices with low-power consumption; (ii) realizing topological superconductors as a platform for Majorana quasiparticles, which hold potential for exotic nonlocal phenomena and quantum computers; and (iii) realizing stable intertwined order in a 3D material with flat energy bands, a research direction I will pioneer with this project.
I will model the proposed setups numerically using low-energy tight-binding models of the materials. The models will be constructed in close collaboration with experimentalists and DFT experts at the host institution MagTop within IF PAN. I will calculate Berry curvature, topological invariants, magnetic order, phase diagrams, and signatures of the emerging phases with regard to charge, spin, and thermal transport. The code used for the calculation of these quantities will be implemented as a software package, which I will utilize and develop during this project. My investigations will provide concrete guidelines for accompanying experimental studies at MagTop. In this way, the outcomes of my project will lay the foundation for tunable topological devices based on chalcogenide superlattices and heterostructures.
