- Description
- Chirality-induced spin selectivity (CISS) is a striking yet still not fully understood effect in chiral chemistry, where electrons gain significant spin polarization when passing through chiral molecules. In this study, we explore CISS in atomically thin chiral crystals formed by van der Waals assembly. We find that the effect can be strong even in just two spin-orbit-coupled monolayers due to the interplay of structural chirality and spin-orbit-induced spin flipping. Focusing on twisted homobilayer transition metal dichalcogenides, our calculations reveal enhanced spin polarization in MoTe₂. These results propose twisted quantum materials as a highly tunable platform for investigating and harnessing the CISS effect in both condensed matter and chiral chemistry.
