In these detectors, 2D materials are typically grown on metallic crystalline substrates and then transferred onto silicon to form a van der Waals junction between the 2D and silicon. In this work, χ₃-phase borophene is directly grown on single-crystal silicon wafers, resulting in excellent Schottky junctions between borophene and silicon. This approach eliminates impurities often introduced during the transfer process, which is commonly performed using polymethyl methacrylate, ensuring a smooth fabrication process and a reliable electrical junction. Optoelectronic measurements of the borophene-based detector on n-type silicon demonstrate high sensitivity, reaching several amps per watt across a wide wavelength range from ultraviolet to infrared. This sensitivity is approximately ten times higher than that of detectors fabricated by transferring 2D materials onto silicon. Additionally, the response times of the fabricated detector are measured at 35 µs for the rise time and 225 µs for the fall time. These exceptional results are attributed to the superior junction formed through direct borophene growth on silicon, paving the way for advanced photodetectors with enhanced light–matter interaction efficiency in integrated silicon-based circuits and technologies.</p>","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 8","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400894","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterized by their large bandgaps, UWBG materials can withstand higher electric fields, operate at elevated temperatures, and achieve greater efficiencies compared to more established semiconductors like silicon and GaAs. These unique properties position UWBG semiconductors as crucial materials for next-generation power electronics, deep-ultraviolet (UV) photodetectors, and high-frequency communication systems.&lt;/p&gt;&lt;p&gt;In recent years, materials such as gallium oxide (Ga&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;), aluminum gallium nitride (Al(Ga)N), and diamond have demonstrated remarkable potential in applications requiring high voltage, high power, and extreme environmental stability. Advances in processing techniques, defect management, and heterostructure design are driving this field forward, enabling devices that are more robust, efficient, and scalable. However, achieving the full potential of UWBG materials still presents significant challenges, including the need for improved material quality, better surface processing techniques, and innovative device architectures.&lt;/p&gt;&lt;p&gt;This special issue of &lt;i&gt;Progresses and Frontiers in Ultrawide Bandgap Semiconductors&lt;/i&gt; brings together seven outstanding contributions that address these challenges and highlight recent breakthroughs in the field. The papers in this issue cover a range of topics, including advanced processing techniques, novel device fabrication methods, defect characterization, and the development of heterostructures for enhanced performance. Together, these works provide a comprehensive snapshot of the state-of-the-art in UWBG semiconductor research and offer insights that will guide future developments.&lt;/p&gt;&lt;p&gt;The following summaries highlight each of these contributions, illustrating the diversity of approaches and the depth of innovation in UWBG semiconductor research.&lt;/p&gt;&lt;p&gt;Brianna Klein and her team from Sandia National Lab and the Ohio State University present an innovative approach in their paper, “Al-Rich AlGaN Transistors with Regrown p-AlGaN Gate Layers and Ohmic Contacts.” This work focuses on fabricating Al-rich AlGaN high electron mobility transistors (HEMTs) with enhancement-mode operation. By employing a deep gate recess etch and epitaxial regrowth of p-AlGaN gate structures, they achieve a large positive threshold voltage (&lt;i&gt;V&lt;/i&gt;&lt;sub&gt;TH&lt;/sub&gt; = +3.5 V) and negligible gate leakage. Additionally, low-resistance Ohmic contacts are realized using regrown, heavily doped, reverse compositionally graded n-type structures, achieving a specific contact resistance as low as 4 × 10&lt;sup&gt;−6&lt;/sup&gt; Ω cm&lt;sup&gt;2&lt;/sup&gt;. These advancements provide a viable pathway for developing high-current, low-leakage, enhancement-mode AlGaN-based ultra-wide bandgap transistors, crucial for future high-power and high-frequency applications.&lt;/p&gt;&lt;p&gt;Xuanyi Zhao and her colleagues from Sha","PeriodicalId":115,"journal":{"name":"Advanced Materials Interfaces","volume":"12 2","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202400993","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143118439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The composition, morphology, and particle size of the functionalized silica are characterized using various physicochemical methods. The material demonstrates high sorption properties for La(III) and Ce(III), both found in Ni-MH batteries, as well as Eu(III). The synthesized functionalized silica, with adsorbed lanthanides, is employed for sensor-based detection of doxycycline in aqueous solutions. After sorbing lanthanides, the bifunctional adsorbent shows a linear response to doxycycline in the concentration range of 0.005–10.0 µ<span>m</span>, with a detection limit of 0.15 µ<span>m</span> L⁻¹ and a quantification limit of 0.44 µ<span>m</span> L⁻¹. The increase in photoluminescence signal upon the addition of doxycycline is explained using Judd–Ofelt theory. Experimental W₂ and W₄ parameters of the Eu-doped nanomatrix are determined to be 1.44 × 10⁻²⁰ cm² and 8.55 × 10⁻²⁰ cm², respectively, with these values increasing to 73.40 × 10⁻²⁰ cm² and 35.58 × 10⁻²⁰ cm² upon the addition of doxycycline. A significant increase in the radiative emission rate from 196 s⁻¹ to 1977 s⁻¹ is observed with doxycycline addition.
