Abstract

Read online

In two-dimensional semiconductors, light can generate spin polarisations, however this effect is typically limited to low temperatures. By combining Lead Iodide (PbI2) with transition metal dichalcogenides (TMDCs), the authors demonstrate room temperature light induced near-unity spin polarisations.
