Solution-Processed NiPS3 Thin Films from Liquid Exfoliated Inks with Long-Lived Spin-Entangled Excitons
Original language description
Antiferromagnets are promising materials for future opto-spintronicapplications since they show spin dynamics in the THz range and nonet magnetization. Recently, layered van der Waals (vdW) antiferromagnetshave been reported, which combine low-dimensional excitonic propertieswith complex spin-structure. While various methods for the fabricationof vdW 2D crystals exist, formation of large area and continuous thinfilms is challenging because of either limited scalability, syntheticcomplexity, or low opto-spintronic quality of the final material.Here, we fabricate centimeter-scale thin films of the van der Waals2D antiferromagnetic material NiPS3, which we prepare usinga crystal ink made from liquid phase exfoliation (LPE). We performstatistical atomic force microscopy (AFM) and scanning electron microscopy(SEM) to characterize and control the lateral size and number of layersthrough this ink-based fabrication. Using ultrafast optical spectroscopyat cryogenic temperatures, we resolve the dynamics of photoexcitedexcitons. We find antiferromagnetic spin arrangement and spin-entangledZhang-Rice multiplet excitons with lifetimes in the nanosecond range,as well as ultranarrow emission line widths, despite the disorderednature of our films. Thus, our findings demonstrate scalable thin-filmfabrication of high-quality NiPS3, which is crucial fortranslating this 2D antiferromagnetic material into spintronic andnanoscale memory devices and further exploring its complex spin-lightcoupled states.
