文摘

The intercalation of metal cations in 2D layered materials allows for the discovery of unique electronic, magnetic and correlated properties. We demonstrate that reversible Li intercalation is also achievable in the hybrid organic/inorganic dimensionally reduced 1D van der Waals solid TiS₂(ethylenediamine). Upon intercalation, electrons are injected into the lattice as Ti⁴⁺ is reduced to Ti³⁺ leading to an order of magnitude decrease in electrical resistivity. This reversible intercalation process opens up new opportunities to fine-tune the physical properties in this emerging family of dimensionally reduced materials.
