However, the major bottleneck requires the growth of large-area WSe 2 single crystals with low defect density, which is essential for practical use. In this study, we present a straightforward atmospheric-pressure chemical vapor deposition method that incorporates Zn ions to facilitate the growth of large-area WSe 2 single crystals with 501 μ m (average size is of 236 μ m). The as-grown WSe 2 exhibits high crystallinity and low defect density ranging from 2.4 × 10 12 cm −2 –3.9 × 10 12 cm −2 . Calculations indicate that the presence of Zn ions effectively reduces the reaction free energy associated with the nucleation and growth of WSe 2 , serving as a critical factor that enhances the growth process. The fabricated WSe 2 field-effect transistors exhibit exceptional electrical performance, achieving a maximum field-effect mobility of 46.02 cm 2 V −1 s −1 and an on/off current ratio of 10 6 . This work provides an effective approach for growing high-quality WSe 2 and holds promise for advancing nanoelectronics with superior performance.","PeriodicalId":6812,"journal":{"name":"2D Materials","volume":"13 1","pages":"015027-015027"},"PeriodicalIF":0.0,"publicationDate":"2026-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895403","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}

However, studying their electronic structures and photophysical processes in layer structures still faces significant challenges. In this work, we synthesized minor and rich Fe ion-doped PA 2 CdCl 4 layer structures by slow-cooling crystallization and adjusting the Fe ion concentration. In minor Fe ion-doped PA 2 CdCl 4 , the Fe–Fe ion pair easily replaces the Cd–Cd pairs in the corner-sharing octahedra layer to form a FMP and promote a red emission (618 nm) from localized exciton-magnetic polarons (LEMPs). In the rich Fe ion doping, AMPs can be easily formed when Fe ions obtain electrons from NH 2 and convert into a low-spin state, coexisting with FMPs. The increasing number of AMPs promote the formation of a new Fe-aniline charge-transfer band; the co-work of AMPs and the Fe-aniline charge-transfer band result in a blue emission (466 nm). The result of the magnetic field-dependent photoluminescence (PL) measurement indicates that the population, energy and the spin direction of AMPs and FMPs can have a direct impact on the luminescence behavior of Fe ion-doped PA 2 CdCl 4 layered structures. The density functional theory (DFT) calculation result indicates that Fe–Fe pairs under ferromagnetic (FM) coupling interact via d x 2 – y 2 and d z 2 orbitals. Fe–Fe pairs under antiferromagnetic (AFM) coupling on the d xy and d z 2 orbitals.

Here, we propose a highly sensitive, stretchable, and transparent multidirectional strain sensor based on patterned vertical graphene array (PVGA) synthesized by plasma-enhanced chemical vapor deposition followed by selective etching and transferring. The obtained PVGA/Polydimethylsiloxane (PDMS) strain sensor exhibits outstanding anisotropic strain sensing performance, including high gauge factor (GF = 85.8 at 10% strain), excellent linearity ( R 2 = 0.99), and outstanding selectivity ( |▽| = 4.17). Cross-plied PVGA/PDMS strain sensors are also fabricated to demonstrate the application of detecting joint movements of the human body, as well as monitoring wrist motion for controlling a fruit-slicer game in the virtual environment. The sensor’s remarkable multi-dimensional sensing performance confirms their significant potential for diverse applications, notably in wearable electronics, such as personal health sensing, artificial intelligence, human-computer interaction, and soft robotics.","PeriodicalId":6812,"journal":{"name":"2D Materials","volume":"12 2","pages":"025006-025006"},"PeriodicalIF":0.0,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147881924","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 structural and electronic properties, synthesis feasibility, piezoelectric properties, and hydrogen evolution reaction were calculated. Our results showed that these 2D Janus MXTe are narrow-gap semiconductors, indicating great conductivity for electrocatalysis. The feasibility of synthesis was comparable to the already synthesized Janus materials. To exhibit a piezoelectrocatalytic effect, the material has to be piezoelectric and catalytically effective simultaneously. As the Janus structure breaks the centrosymmetry, the considered MXTe are intrinsically piezoelectric. We therefore calculated the dipole moments and the variation of out-of-plane polarization upon strain. The computed piezoelectric coefficient e31 is within the same order of magnitude as that of other Janus 2D materials. Finally, although pristine 2D Janus MXTe were inert to hydrogen evolution reaction, incorporation of single-atom defects was found to boost hydrogen adsorption significantly. The catalytic efficacy can be further tuned by biaxial tensile strain, effectively controlling the Gibbs free energy of adsorption to be close to the thermoneutral value that is indicative of an excellent hydrogen evolution reaction activity, at least for ZrSTe Janus monolayer. In summary, this work proposed and comprehensively investigated a new class of possible piezoelectrocatalysts, 2D Janus materials, which is feasible to be synthesized, catalytically effective, and has great conductivity.","PeriodicalId":6812,"journal":{"name":"2D Materials","volume":"194 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254944","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}
