Summary: We investigate the photo-generated dynamics in 2D heterostructures and find that there is no charge transfer between PbI2 and MoSe2, but the photoluminescence changes of MoSe2 are dominated by interlayer charge transfer. Density functional theory calculations show that the binding energies in MoSe2/WSe2 or MoSe2/MoS2 heterostructures are 2-3 times higher than that in MoSe2/PbI2 heterostructure, indicating weaker interlayer coupling between MoSe2 and PbI2. These findings are crucial for fundamental research and applications of novel optoelectronic devices based on 2D material heterostructures.

Summary: The evaluation of perovskite (CH3NH3PbI3) films prepared using PbI2 film deposited at controlled deposition rates was conducted. PbI2 films were deposited by vacuum evaporation process and then converted into CH3NH3PbI3 films by annealing in methylammonium iodide vapor. The grain size of CH3NH3PbI3 films was successfully controlled from 90 to 125 nm by adjusting the PbI2 deposition rate from 0.025 to 0.4 nm s(-1). Furthermore, by using the controlled CH3NH3PbI3 film as the light harvesting layer, inverted planar perovskite solar cells were fabricated, leading to an improvement in power conversion efficiency.

Summary: We present the performance of self-powered UV photodetectors composed of SnO2 nanowire networks. The synthesis of SnO2 nanowires with a length of several hundred micrometers was achieved using thermal chemical vapor deposition (CVD) at low process temperatures without a reducing agent. The growth behavior of the nanowires was determined through characterization methods, and the device exhibited a high photo-to-dark current ratio and responsivity to UV light in the deep UV range. The results show that SnO2 nanowires have great potential for self-powered UV photodetectors and can be synthesized at low temperatures using SnO powder.

The ETL selection influences the growth of PbI2 and its reaction to MAPbI3, resulting in different morphological and crystallographic properties. Compact films with reasonable morphology can be obtained on each ETL. The ETL choice also affects the reaction rate and the performance of solar cells, as well as hysteresis and air stability.

Summary: Metal nanocrystals exhibit antithetical mechanical behaviors, with smaller crystals either showing increased strength or decreased strength. The mechanisms governing these behaviors, including dislocation-starvation induced strengthening and surface diffusion induced softening, are not fully understood. To investigate this, sub-20-nm Au and Co nanocrystals were studied using electrical loading-coupled transmission electron microscopy to create variable temperature conditions. It was found that surface diffusion is more temperature-sensitive than dislocation activities and deformation mechanisms transition when surface diffusion is activated or inhibited. At elevated temperatures, the nanocrystals exhibit liquid-like behaviors with consecutive surface reshaping or collapse-and-reconstruction shape transformations taking place. (c) 2023 Elsevier Ltd.

Summary: In this study, hydrothermally synthesized Te nanosheets were investigated at different growth stages using transmission electron microscopy and electrical tests. Three main types of Te nanosheets and their variations were identified. Different types of Te nanosheets dominated at different reaction stages, suggesting a sequential growth scenario. The growth kinetics were co-determined by surfactants and surface energy, while crystallographic attachments resulted in specifically included angles in V-shaped Te nanosheets. The fractions of different types of Te nanosheets, as well as their crystalline structures, interfaces, and preferential growth orientations, were statistically tracked. Additionally, the electrical properties of the Te nanosheets showed an interface-related feature. These findings provide new insights into the synthesis and properties of low-dimensional Te functional materials.

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.
