Hypothesis
How does chirality affect spin angular momentum in hybrid metal/chiral molecule systems?
Conclusion
Chiral molecules induce unidirectional spin-to-charge conversion with maximum spin selectivity along the molecular axis.
Supporting Evidence
- Chiral-induced spin selectivity has been observed with efficiencies over 70%.
- The study shows that the spin selectivity is maximum when the spin angular momentum aligns with the molecular chiral axis.
- The results confirm that spin angular momentum plays a crucial role in the CISS effect.
Takeaway
Chiral molecules can change how spins in electrons behave, making them move in one direction more than the other.
Methodology
Spin pumping experiments were performed in ferrimagnetic insulator/heavy metal bilayer structures to generate a pure spin current.
