Summary: Layered van der Waals (vdW) antiferromagnets with low-dimensional excitonic properties and complex spin-structure are promising materials for future opto-spintronic applications. In this study, we successfully fabricated centimeter-scale thin films of the 2D antiferromagnetic material NiPS3 using liquid phase exfoliation. The films showed antiferromagnetic spin arrangement, spin-entangled Zhang-Rice multiplet excitons, and ultranarrow emission line widths, despite their disordered nature. These results demonstrate the scalable thin-film fabrication of high-quality NiPS3, which is crucial for utilizing this material in spintronic and nanoscale memory devices and exploring its complex spin-light coupled states.

Summary: This study investigates the surface properties and defects of organic-inorganic hybrid perovskite materials using low-temperature scanning tunneling microscopy. Atomic-resolution imaging reveals flat surface structures, atomic steps, and crystal grain boundaries, while defects are characterized. It is also observed that tip scanning induces the migration of surface iodine ions, leading to the instability of the surface iodine lattice structure.

Summary: This study reports the improvement of electronic properties of solution-processed indium oxide films by adding an organic p-type semiconductor material, resulting in organic-inorganic hybrid TFTs. The addition of TIPS-pentacene enhances electron mobility, improves electronic stability, and reduces the number of required spin-coating steps. The hybrid TFTs exhibit either enhancement- or depletion-mode behavior depending on the fabrication process, showing potential for the construction of organic-inorganic hybrid electronics and circuits.

Summary: Experimental realization of thin films with significant room-temperature magnetoelectric coupling coefficient α(ME) without an external DC magnetic field has been challenging. Here, large α(ME) of 750 +/- 30 mV Oe(-1) cm(-1) is achieved in multiferroic polymer nanocomposites (MPCs) thin films. The MPCs consist of PMMA-grafted cobalt-ferrite nanoparticles uniformly dispersed in piezoelectric polymer P(VDF-TrFE). Nanoparticle agglomeration is reduced by surface functionalization with PMMA, enabling the uniform dispersion of nanoparticles in submicrometer thin films. This research can promote the development of flexible and printable multiferroic electronic devices for sensing and memory applications.
