The sensitivity and pressure-sensing range of current humanoid tactile sensors have performed significant advancements. However, the temperature susceptibility of conductive materials and the rapid saturation of conductive contact sites in soft polymeric materials bring about challenges for these sensors, including environmental interference and a narrow linear sensing range. These issues lead to the inconsistencies between the sensing signal and contact behavior, which eventually deteriorates both the accuracy and reliability. Here, we propose a flexible piezoresistive pressure sensor with minimized response to temperature variation but extended linear sensing range. The sensor utilizes a novel hybrid conductive material elaborated to exhibit zero temperature resistance coefficient by combining the materials with the opposite temperature coefficients, which allows for a reliable operation ranging from 20 to 70 ℃ with temperature variation induced fluctuation free. Additionally, the sensor provides a biomimetic polymer microstructure with multilevel cone-dome structural feature, which results in an ultra-wide linear pressure-sensing range from 0 up to 200 kPa. In addition, based on the simple and scalable fabrication process, a high-density sensor array (16×16) is produced to outline the spatial pressure distributions accurately even under the external temperature interferences and successfully discern the texture of the contact object.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"17 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To approach its optimal performance, it would be helpful to reveal the electrical and photoelectric properties within its core regions from a microscopic perspective. Herein, we employed cross-sectional scanning capacitance microscopy (SCM) to investigate the photocarrier behaviors in two APD devices under excitation of different light wavelengths. The grading and charge layers as well as the multiplication regions of the APDs were well resolved electrically in this study. The light-induced capacitance response in the multiplication region was found to differ by 2–4 times in the two devices, signifying a much higher photocarrier concentration under the same excitation intensity. Additionally, a sharp gradient of capacitance was observed along the core regions, which directly reflects the pronounced drifting of photocarriers in the strong built-in electric field. The findings of this study substantiate the low dark current and high gain merits of the APD device, providing an effective strategy to explore the spatial and physical origin of the device performance through nanoscopic observation of carriers in the active area.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"56 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is well known that the quality of tips become the crucial issue of TERS technology. Therefore, the development on the cost-effective and feasible method for fabricating AFM-TERS tips with stable TERS imaging capabilities is high desired. Herein, a facial approach combining the nanoparticles assembly with electrodeposition has been developed to fabricate AFM-TERS tips. The different fabrication recipes were carefully compared to identify the most suitable approach. Utilizing p-nitrobenzenethiol (pNTP) as the probe molecule, the results revealed that annealing treatment, coupled with the electrochemical deposition of additional outer layers of gold, significantly improved the stability and cleanness of the tips. Annealing at 105°C followed by the electrodeposition of a 10 nm outer layer of gold brought tips with a controllable morphology, featuring a radius of curvature (ROC) of approximately 35 nm, and an enhancement factor of roughly 3.2 × 104. The present results suggested that the approach become one of the promising tools and can be served as a general routine for the cost-effective fabrication of AFM-TERS tips for extending the practical application of TERS technology.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"286 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The S-MRH composite, synthesized via a salt-assisted method without toxic chemicals, features amorphous polar SiOx and porous carbon working synergistically. SiOx promotes a catalytic effect that suppresses polysulfide dissolution, while porous carbon provides an open conductive network. An S-MRH-coated polypropylene (S-MRH/PP) separator exhibited a high specific capacity of 1507.7 mA h g−1 at 0.1C, which is attributed to improved sulfur utilization. Compared to different separators, the S-MRH/PP separator demonstrated a superior rate performance of 766.5 mA h g−1 at 3C. Even under high sulfur loading and lean electrolyte conditions, S-MRH/PP exhibited good cycling stability with high capacities. This study highlights the potential of biomass-derived materials in Li–S batteries and offers insights into SiOx/C synthesis applicable to various energy storage systems.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"125 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143920356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For many systems, although there have been plenty of studies on the monolayer ferroelectrics, the bilayer or multilayer ferroelectricity has been rarely investigated. Here, we focus on the sliding ferroelectricity of bilayer α- and β-phase MX (M = Si, Ge, Sn and Pb; X = S, Se and Te) structures. Bilayer α-SiS is found to exhibit a quite large out-of-plane polarization that is not present in the monolayer configuration. Interestingly, the polarization of bilayer β-MX shows a periodic variation with the change of X atoms, where the charge transfer is found to play an important role. Furthermore, both strain and multilayer stacking are found to be able to effectively modulate the polarization. With those structures, field-effect transistors (FETs) are constructed and their performances are found to satisfy the International Technology Roadmap for Semiconductors (ITRS) requirements for the year of 2028. Moreover, four kinds of logic operators are proposed and also demonstrated to operate quite well, showing great application potential.
