Summary: This study presents a dual active layer structure of indium-zinc oxide (InZnO) and indiummagnesium-zinc oxide (InMgZnO) fabricated using a simple solution process. By utilizing a heterojunction structure and optimizing the front channel thickness, as well as treating the heterojunction interface with oxygen plasma, the researchers achieved thin-film transistor (TFT) devices with enhanced performance and greater stability. The high electrical performance and stability of the heterojunction TFTs can be attributed to the reduced interfacial defect state achieved through oxygen plasma treatment and the electron redistribution occurring at the heterojunction interface.

Summary: In this study, a novel approach to improve charge transport and device performance in two-dimensional RP CsPbI3 perovskite solar cells (PSC) was proposed by developing a multiple-ring aromatic spacer. The use of 1-naphthylamine (1-NA) spacer with extended pi-conjugation lengths was found to reduce the exciton binding energy and facilitate efficient separation of excitons. The cations of the spacer also made a significant contribution to the conduction band, leading to a reduced bandgap and improved interlayer charge transport. The strong pi-pi conjugation of the spacer enhanced intermolecular interactions and hydrogen bonding, resulting in high-quality films with preferred vertical orientation and lower defect density. The (1-NA)(2)(Cs)(3)Pb4I3 PSC achieved a record 16.62% performance with enhanced stability.

Summary: Perovskites, as one of the most promising candidates for X-rays imaging materials, have received extensive attention. However, poor stability and undesirable ion migration hinder their development. In recent years, two-dimensional (2D) perovskite materials have been successfully developed to address these issues, but the preparation of pure phase single crystals remains challenging. This study demonstrates the use of a 2D perovskite single crystal, BA(2)PbBr(4), as a representative model, grown using a simple solution temperature lowering (STL) synthesis method. The crystal exhibits a short fluorescence lifetime, intense X-rays radioluminescence, and high environmental and temperature stability. It has also been used in X-rays imaging, showing good imaging results and stability. This research highlights the great potential of 2D perovskites in low-cost X-rays imaging systems.

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.
