Summary: In this study, CuCrS2 nanoflakes were successfully synthesized by salt-assisted chemical vapor deposition, demonstrating switchable ferroelectric polarization even at a thickness of 6 nm. The high T-C of around 700 K can be attributed to the robust tetrahedral bonding configurations of Cu cations, with further clarification provided by a theoretically predicted high order-disorder transition barrier and structure evolution from 600 to 800 K. Additionally, interlocked out-of-plane and in-plane ferroelectric domains were observed, leading to the demonstration of two devices based on different polarizations.

Summary: The growth of 2D-BN was studied using independent boron and nitrogen sources in a plasma-assisted molecular beam epitaxy set-up. The growth conditions on polycrystalline Ni foils, including B and N fluxes, temperature, and time, were found to influence the surface morphology, stoichiometry, and domain size of 2D-BN. Different precursor flux ratios led to different compositions of the film, with either excess boron or stoichiometric 2D-BN. The optimized growth temperature was 900 degrees C, which improved the crystallographic quality but also caused partial sublimation of BN.
