The coverage of V-pits in InGaN/GaN multi-quantum wells (MQWs) is critical for suppressing leakage path through electron blocking layer (EBL). In this study, we have investigated the coverage of V-pits in green mini-LEDs modulated via growth parameters optimization and systematically analyzed the characteristics of the photoelectric properties associated with V-pits coverage on device. Elevated temperatures and pressures result in enhanced adatoms migration, which can achieve a coverage up to 98.8% of V-pits, improving the crystal quality due to stable surface. Electrical characterization reveals that although high-coverage devices exhibit suppressed leakage current, their peak external quantum efficiency (EQE) decreases, more seriously spectral blue shift and operating voltage increase due to compromised hole transport uniformity. Intriguingly, intermediate-coverage samples demonstrate superior breakdown voltage characteristics. Current–voltage curve analysis shows the ideality factor increases from 1.8 to 2.5 with improved coverage, indicating aggravated Shockley–Read–Hall (SRH) recombination with covered V-pits.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review critically examines the strategic engineering of oxygen vacancies (OVs) as a powerful tool for overcoming these intrinsic limitations. We systematically analyze established methodologies for the deliberate introduction and modulation of OVs in metal oxides, including techniques such as the hydrothermal method, thermal treatment, chemical reduction, plasma processing, elemental doping, and microwave heating. Furthermore, we critically evaluate the applicability, strengths, and limitations of key characterization techniques for detecting and quantifying OVs. Crucially, the review delves into the profound mechanistic impacts of OVs on the PEC process chain: Their roles in tailoring electronic band structures to alter the photoelectrochemical properties of metal oxide photoanodes, thereby enhancing visible light absorption, acting as shallow donors to improve charge carrier density, functioning as electron traps to suppress bulk recombination, and modifying surface states to accelerate the oxygen evolution reaction. We also present detailed case studies focusing on five prominent photoanode materials: TiO2, α-Fe2O3, BiVO4, WO3, and ZnFe2O4. This review elucidates the specific roles and operational principles of OVs within these materials and summarizes the intrinsic relationship among OV generation, characterization, and functional enhancement, providing valuable insights for the rational design of OV-engineered photoanodes toward efficient solar fuel production.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rare-earth-doped upconversion nanoparticles (UCNPs), renowned for their unique luminescence properties, large anti-Stokes shift, excellent biocompatibility, and deep tissue penetration, have emerged as highly promising candidates for advanced phototherapy in biological systems. This review first explores the fundamental mechanisms of upconversion luminescence, as well as synthesis, surface modification, and design strategies to brighten upconversion. It then highlights recent advances and key applications of UCNPs in biological therapy, including upconversion-mediated phototherapy, multimodal therapeutic approaches, and image-guided therapy and surgery. Finally, it discusses the current challenges and opportunities in both fundamental research and clinical translation, providing theoretical insights and practical guidance to support the broader application of UCNPs in biological therapy and clinical medicine.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70012","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, Te vacancies in form of Bi2Te3−x are proposed to polarize the PVH unit to realize efficient decoupling of lithium salts at the atomic level in PVH-based solid polymeric electrolyte. Te vacancies in the PVH electrolyte doped with Bi2Te3−x (PVBT) induce a high-throughput and homogenous Li+ flow within the PVH matrices and near the Li metal. Theoretical calculations show that Te vacancies own high adsorption energy with bis(trifluoromethanesulfonyl)imide anions (TFSI−), repulsive effect on Li+, and localized electron distribution, giving rise to a lithium-ion concentration gradient of 30 mol m−3, the smallest among the PVH-based inorganic/organic composite electrolytes. Consequently, the polarized electrolyte owns an unprecedented high-rate battery capacity of 114 mAh g−1 at ∼700 mA g−1 and also superior capacity performances with a cathode loading of 12 mg cm−2, outperforming the state-of-art PVH-based inorganic/organic composite electrolytes in Li||LiFePO4 battery. The work demonstrates an efficient strategy for achieving fast Li+ diffusion dynamics across polymeric matrices of classic solid-state electrolytes.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we provide a simple and scalable preparation of VO2(M2) nanorods on TiO2 nanoparticles decorated flexible glass fiber cloth (GFC) by hydrothermal and subsequent annealing process. Because of the interfacial strain between TiO2 and VO2, M2 phase VO2 nanorods were successfully fabricated and verified. The resultant VO2(M2)/GFC composite demonstrates a remarkable resistance change (∼3.4 × 104) across the phase transition, which is superior to the films prepared by vacuum chamber-based techniques. Meanwhile, it also demonstrates 13.1 times enhanced electromagnetic shielding efficiency and favorable emissivity modulation capability. The flexible and scalable preparation of VO2(M2) will broaden the promising applications of the material in both optical and electronic devices.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
