Transition metal dichalcogenides (TMDs) on magnetic substrates exhibit proximity-induced ferromagnetism. This enables tunable spin-polarized currents in one-dimensional conducting channels for spintronics applications.
Area of Science:
- Condensed Matter Physics
- Materials Science
- Spintronics
Background:
- Transition metal dichalcogenides (TMDs) are promising 2D materials.
- Proximity effects in layered materials are of significant interest.
- Ferromagnetic substrates can induce novel electronic properties.
Purpose of the Study:
- To investigate proximity-induced ferromagnetism in molybdenum ditelluride (MoTe2) nanoribbons.
- To explore the role of magnetic substrates like europium oxide (EuO).
- To understand the formation of tunable spin-polarized currents.
Main Methods:
- Utilized a tight-binding model.
- Incorporated exchange and Rashba fields.
- Simulated electronic modes in nanoribbons with zigzag edges.
Main Results:
- Observed edge-localized electronic modes acting as 1D conducting channels.
- Demonstrated tunable spin-polarized currents at in-gap Fermi levels.
- Showcased the influence of proximity to ferromagnetic substrates.
Conclusions:
- TMDs on magnetic substrates offer a platform for proximity-induced ferromagnetism.
- These systems are valuable for spintronics research.
- Edge states provide tunable spin currents in complex 1D systems.
