However, the absence of a reliable room temperature n-type transport has impeded any advancements in diamond-based electronics. Here, we circumvent this bottleneck by integrating n-type two-dimensional (2D) monolayers of molybdenum disulfide (MoS2) with boron doped p-type single crystal diamond and demonstrate 2D/3D heterostructure-based PN junction diodes that operate at room temperature with excellent rectification characteristics. Our diodes achieve a maximum forward current density (JD) of ∼4000 A/cm2, an ideality factor (η) value of ∼3.7, and a rectification ratio (RR) of 106. We find that the origin of current rectification stems from the interlayer recombination of majority carriers driven by direct tunnelling (DT) and Fowler Nordheim (FN) tunnelling mechanisms. Our demonstration can open new avenues for diamond-based power electronics through its integration with 2D materials.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"27 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is accounted for via generalized, position-dependent friction-coefficient and interfacial viscosity profiles, which enable the accurate description of interfacial flow at the nanoscale using the Stokes equation. Such profiles are extracted from nonequilibrium molecular dynamics simulations of water on polar, nonpolar, fluorinated, and unfluorinated alkane and alcohol self-assembled monolayers spanning a wide range of wetting characteristics. The Navier friction coefficient, interfacial viscosity excess, and depletion length are found to be interrelated through power laws and to scale exponentially with the work of adhesion.

In this work, the typical narrow bandgap semiconductor of GaSb nanowire (NW) is demonstrated as a competitive candidate for infrared spectral encryption by modulating the photodetection wavelength. The bandgap of GaSb NW is controlled from 0.72 to 1.28 eV, benefiting the tunable photodetection wavelength range of 1550-785 nm. As a result, an infrared spectral encryption is realized by a GaSb NW with four different bandgaps. The controlled bandgap results from the successful growth of the GaNSb ternary alloy during the easily handled and low-cost chemical vapor deposition process. In the end, infrared spectral encryption is demonstrated as a code lock of a door, covering advanced cryptographic needs.

Inspired by the skin surface structure of a desert lizard, we propose an integrated thermal-wet comfort (i-TWC) textile featuring a gradient wetting structure. The design of the sweat gland-like sweat-wicking channel endows the i-TWC textile with an impressive 2 s one-way sweat transfer capability. Meanwhile, the introduction of a triboelectric field accelerates the evaporation of perspiration in the hydrophilic layer, ensuring the stability of the one-way water transfer. It is worth noting that the synergistic effects of the bioinspired sweat gland structure and triboelectric field result in a significantly improved evaporation rate (increased from 0.17 to 0.33 g h-1) and show some potential for passive cooling of the human body (1.07 °C).

In this work, we report three coordination polymers (CPs) with cofacial translational stacking (H-aggregation), cofacial-staggered translational stacking (H-J aggregation) and cofacial translational-crossing stacking (H-X aggregation): [Zn(3,4-PyDC)(TPT)]·TPT (1; 3,4-PyDC = 3,4-pyridinedicarboxylate; TPT = 2,4,6-tri(4-pyridyl)-1,3,5-triazine), [Zn(IPA)(TPT)2]·H2O (2; IPA = isophthalate) and [Zn3(3,5-PyC)2(TPT)3(H2O)2] (3; 3,5-PyC = 3,5-pyrazoledicarboxylate). By changing the aggregation modes, these CPs exhibit tunable triplet exciton pathways, enabling distinct fluorescent, phosphorescent, and photochromic properties. Single-crystal X-ray diffraction, time-resolved emission spectroscopy and theoretical analysis demonstrate that enhanced charge migration in 2 with H-J aggregation promotes charge-separated photochromism, while differentiated orbital energies in 3 with H-X aggregation enables wavelength-responsive room temperature phosphorescence. These findings provide a route to hybrid CPs with designated triplet-exciton pathways and associated optical properties by manipulating molecular aggregation.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"114 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This orbit-BPVE is contributed by the chirality-dependent orbital angular momentum (OAM), and the chirality-locked spin-BPVE is a secondary effect arising from the orbit-BPVE, mediated by spin-orbit coupling (SOC). The minimal-model calculations further demonstrate that the robust orbit-BPVE persists even at small screw angles and varying SOC strength, and the orbit-BPVE remains more pronounced than spin-BPVE in a wide range of SOC strengths.

H-Fe@C exhibited superior performance in lithium-metal anodes, achieving stable cycling for over 2500 h with exceptional overpotentials as low as 7.4 mV and 76% capacity retention after 1000 cycles, significantly outperforming U-Fe@C due to enhanced mass transport through the thin carbon shell (∼50 nm).
