Summary: Two-dimensional hybrid perovskites, especially ferroelectric crystals, have great potential in optoelectronics as polarized light detectors. In this study, exceptional polarization responses to polarized light were achieved in ferroelectric crystals of (isopentylammonium)(2)CsPb2Br7. The alternate packing of organic spacers and inorganic sheets leads to its intrinsic optical dichroism, creating sinusoidal photocurrents with a polarization ratio of approximately 1.2 at 10 V bias. Notably, a large polarization ratio of approximately 7.2 can be obtained based on its bulk photovoltaic effect at zero bias (self-powered mode). This work sheds light on optimizing photoelectric behaviors in targeted optoelectronic device applications through ferroelectric bulk photovoltaic effect.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
