Low-dimensional Ga2O3 monocrystalline micro/nanostructures show promising application prospects in largearea arrays, integrated circuits, and flexible optoelectronic devices, owing to their exceptional optoelectronic performance and scalability for mass production. Herein, we developed an 8 x 8 array of high-performance solar-blind ultraviolet photodetectors based on Pt nanoparticles-modified Ga2O3 (PtNPs@Ga2O3) nanorod film heterojunction with p-GaN substrate serving as the hole transporting layer. The PtNPs@Ga2O3/GaN heterojunction detector units exhibit outstanding photovoltaic performance at 0 V bias, demonstrating high responsivity (189.0 mA/W), specific detectivity (4.0 x 1012 Jones), external quantum efficiency (92.4%), and swift response time (674/692 mu s) under an irradiance of 1 mu W/cm2 at 254 nm. Their exceptional performance stands out among competitors of the same type. In addition, the detector array demonstrated satisfactory results in a conceptual demonstration of high-resolution imaging, benefiting from the excellent stability and uniformity exhibited by its array units. These findings provide a straightforward and viable method for developing a high-performance solar-blind ultraviolet detector array based on low-dimensional Ga2O3 nanorod monocrystalline, demonstrating their potential advancement in large-area, integrable, and flexible optoelectronic devices.

E-PRedictor: an approach for early prediction of pull request acceptance

引用

Science China(Information Sciences) 2025年

作者： Kexing CHEN Lingfeng BAO Xing HU Xin XIA Xiaohu YANG State Key laboratory of Blockchain and Data Security Zhejiang University Software Engineering Application Technology lab

A pull request (PR) is an event in Git where a contributor asks project maintainers to review code he/she wants to merge into a project. The PR mechanism greatly improves the efficiency of distributed software development in the opensource community. Nevertheless, the massive number of PRs in an open-source software (OSS) project increases the workload of developers. To reduce the burden on developers, many previous studies have investigated factors that affect the chance of PRs getting accepted and built prediction models based on these factors. However, most prediction models are built on the data after PRs are submitted for a while (e.g., comments on PRs), making them not useful in practice. Because integrators still need to spend a large amount of effort on inspecting PRs. In this study, we propose an approach named E-PRedictor (earlier PR predictor) to predict whether a PR will be merged when it is created. E-PRedictor combines three dimensions of manual statistic features (i.e., contributor profile, specific pull request, and project profile) and deep semantic features generated by BERT models based on the description and code changes of PRs. To evaluate the performance of E-PRedictor, we collect475192 PRs from 49 popular open-source projects on GitHub. The experiment results show that our proposed approach can effectively predict whether a PR will be merged or not. E-PRedictor outperforms the baseline models (e.g., Random Forest and VDCNN) built on manual features significantly. In terms of F1@Merge, F1@Reject, and AUC (area under the receiver operating characteristic curve), the performance of E-PRedictor is 90.1%, 60.5%, and 85.4%, respectively.

Is p-Type Doping in SeO₂ Feasible?

引用

CHINESE PHYSICS LETTERS 2025年第2期42卷 72-77页

作者： Xiao, Zewen Huazhong Univ Sci & Technol Wuhan Natl Lab Optoelect Wuhan 430074 Peoples R China

p-type transparent oxide semiconductors (TOSs) are significant in the semiconductor industry, driving advancements in optoelectronic technologies for transparent electronic devices with unique properties. The recent discovery of p-type behavior in SeO2 has stimulated interest and confusion in the scientific community. In this Letter, we employ density functional theory calculations to reveal the intrinsic intrinsic insulating characteristics of SeO2 and highlight the substantial challenges in carrier doping. Our electronic structure analyses indicate that the Se 5s2 states are energetically positioned too low to effectively interact with the O 2p orbitals, resulting in a valence band maximum (VBM) primarily dominated by the O 2p orbitals. The deep and localized nature of the VBM of SeO2 limits its potential as a high-mobility p-type TOS. Defect calculations demonstrate that all intrinsic defects in SeO2 exhibit deep transition levels within the bandgap. Regardless of the synthesis conditions, the Fermi level consistently resides in the mid-gap region. Furthermore, deep intrinsic acceptors and donors exhibit negative formation energies in the n-type and p-type regions, respectively, facilitating spontaneous formation and impeding external doping efforts. Thus, the reported p-type conductivity in SeO2 samples is unlikely to be intrinsic and is more plausibly attributable to reduced elemental Se, a well-known p-type semiconductor.

Independent and interactive effects of N and P additions on foliar P fractions in evergreen forests of southern China

Fertilization or atmospheric deposition of nitrogen (N) and phosphorus (P) to terrestrial ecosystems can alter soil N (P) availability and the nature of nutrient limitation for plant growth. Changing the allocation of leaf P fractions is potentially an adaptive strategy for plants to cope with soil N (P) availability and nutrient-limiting conditions. However, the impact of the interactions between imbalanced anthropogenic N and P inputs on the concentrations and allocation proportions of leaf P fractions in forest woody plants remains elusive. We conducted a meta- analysis of data about the concentrations and allocation proportions of leaf P fractions, specifically associated with individual and combined additions of N and P in evergreen forests, the dominant vegetation type in southern China where the primary productivity is usually considered limited by P. This assessment allowed us to quantitatively evaluate the effects of N and P additions alone and interactively on leaf P allocation and use strategies. Nitrogen addition (exacerbating P limitation) reduced the concentrations of leaf total P and different leaf P fractions. Nitrogen addition reduced the allocation to leaf metabolic P but increased the allocation to other fractions, while P addition showed opposite trends. The simultaneous additions of N and P showed an antagonistic (mutual suppression) effect on the concentrations of leaf P fractions, but an additive (summary) effect on the allocation proportions of leaf P fractions. These results highlight the importance of strategies of leaf P fraction allocation in forest plants under changes in environmental nutrient availability. Importantly, our study identified critical interactions associated with combined N and P inputs that affect leaf P fractions, thus aiding in predicting plant acclimation strategies in the context of intensifying and imbalanced anthropogenic nutrient inputs.

Short rotation plantation forestry (SRF) is being widely adopted to increase wood production, in order to meet global demand for wood products. However, to ensure maximum gains from SRF, optimised management regimes need to be established by integrating robust predictions and an understanding of mechanisms underlying tree growth. Hybrid ecophysiological models, such as potentially useable light sum equation (PULSE) models, are useful tools requiring minimal input data that meet the requirements of SRF. PULSE models have been tested and calibrated for different evergreen conifers and broadleaves at both juvenile and mature stages of tree growth with coarse soil and climate data. Therefore, it is prudent to question: can adding detailed soil and climatic data reduce errors in this type of model? In addition, PULSE techniques have not been used to model deciduous species, which are a challenge for ecophysiological models due to their phenology. This study developed a PULSE model for a clonal Populus tomentosa plantation in northern China using detailed edaphic and climatic data. The results showed high precision and low bias in height (m) and basal area (m2 center dot ha-1) predictions. While detailed edaphoclimatic data produce highly precise predictions and a good mechanistic understanding, the study suggested that local climatic data could also be employed. The study showed that PULSE modelling in combination with coarse level of edaphic and local climate data resulted in reasonably precise tree growth prediction and minimal bias.

Ca2+/Cr3+ co-doped LaAlO3 infrared (IR) ceramics have been proven to be potential energy-saving materials for high- temperature industries because of their high emissivity and high- temperature stability. However, Cr6+ formation commonly occurs in materials and poses environmental and health risks, such as Cr6+ dissolution in water and CrO3(g) volatilization. In this study, we combined high emissivity with in situ detoxification by introducing residual Al2O3 into Ca2+/Cr3+ co-doped LaAlO3 ceramics. Compared with the undoped ceramics, the addition of 20 wt% residual Al2O3 resulted in a 78.5% reduction to 18.44 mg/kg (lower than the EU standard of 20 mg/kg) in Cr6+ dissolution and a decrease in 77.8% CrO3(g) volatilization. This significant detoxification effect can be attributed to the formation of CaAl12-xCrxO19. Additionally, as the residual Al2O3 content increased from 5 to 20 wt%, the ceramics maintained high emissivity, above 0.896 in the near-infrared band and 0.781 in the mid-infrared band. Furthermore, the IR coating effectively increased the surface temperature (from 767.1 to 790.7 degrees C/min) and the heat radiation of the heating source, increasing the heating rate from 31.7 to 34.6 degrees C/min during water heating. This work offers a promising approach for designing environmentally friendly IR ceramics with excellent IR performance for energy-saving applications in the high-temperature industry.
