By combining spectral heat current decomposition and spectral energy density analysis, we identify high-frequency optical phonons within 10–15 THz as the dominant heat carriers across interfaces—a selectivity arising from interfacial hydrogen termination that strengthens the coupling of these modes. Their lifetimes and coupling strengths are highly sensitive to structural configuration and mechanical modulation. Our results reveal that parallel stacking, increased pressure, and stronger interlayer coupling significantly enhance thermal conductivity by stabilizing optical modes and suppressing phonon scattering. In contrast, increasing the twist angle introduces structural incommensurability, which reduces phonon lifetimes and leads to substantial suppression of thermal transport. These findings underscore the pivotal role of optical phonons in governing interfacial thermal transport as well as establish an optimal strategy for engineering thermal conductivity in 2D vdW materials.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"53 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145235032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While most studies have focused on thick or bulk films with negligible DC offset-induced Joule heating, systematic studies of the DC offset effect in thin films have been lacking. Here, we investigate the anomalous Ettingshausen effect (AEE) in magnetic thin films, including Ni(10 nm), CoFeB(6 nm), and CoFeB(6 nm)/Ru(0.6 nm)/Ni(10 nm) synthetic antiferromagnets, using the LIT under varying DC offset and magnetic field conditions. We show theoretically that, instead of adversely affecting LIT measurements, an intentionally introduced DC offset with moderate magnitude facilitates the extraction of AEE signals, which is verified experimentally through measurement of hysteresis loops of different types of U-shaped samples. Our findings show LIT's potential for studying magneto-thermoelectric effects in single- and multilayer structures over a broad thickness range, beyond just thick films.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"348 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145234985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, perovskite Sr0.6Ba0.4TiO3 (SBT) is introduced into tungsten bronze Sr0.6Ba0.4Nb2O6 (SBN), maintaining an identical Sr/Ba ratio, to enhance the energy storage performance of Bi/Na/Pb-free (1 − x)SBN-xSBT ferroelectrics. The sample with increasing x ≤ 0.3 forms a solid solution corresponding to the unfilled–filled tungsten bronze structure transition, accompanied by dramatically decreased grain anisotropy and average grain size. However, the perovskite second phase gradually appears, and the average grain size further decreases slightly when x > 0.3. Such phase and microstructure evolution induces monotonously enhanced relaxor degree γ and breakdown strength Eb around x = 0.4. As a result, this optimal composition shows high recoverable energy storage density Wrec = 9.5 J/cm3, energy storage efficiency η = 82.1%, both of which vary less than 7% within 20–150 °C. Encouragingly, excellent charge–discharge performances, t0.9 = 23 ns and WD = 6.2 J/cm3, are obtained.

Traditional biosensing techniques, such as electrochemical, fluorescence, and colorimetric methods, have shown remarkable performance. However, their reliability is often susceptible to nonspecific interference, may produce false-positive results, and is typically limited to the detection of known targets, restricting their applicability in addressing ambiguous or unknown biological problems. Surface-enhanced Raman scattering (SERS) offers a powerful alternative, combining ultra-high sensitivity and molecular specificity. By supporting both label-free and label-based strategies, SERS broadens the detection scope, making it a promising platform for next-generation biosensing. In this Perspective, we aim at specific problems, introduce why SERS can do biosensing, how to advance SERS-based biosensing, and what SERS can do for early diagnosis. Finally, we discuss strategies to bridge the gap between laboratory research and clinical applications, emphasizing the important role of standardization and artificial intelligence in driving the practical transformation of SERS-based biosensing. Through these advancements, we aim to address existing limitations and further propel the evolution of SERS in biosensing and early diagnosis.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"6 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145228947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meanwhile, benefiting from the inherent configuration of the double-acting design, the four-cylinder arrangement further enhances the system's power density, thereby improving its suitability for industrial heating applications. Experimental results demonstrate that the system achieves a substantial temperature lift from 25 to 166 °C, and within a temperature difference of 74 °C (from 45 to 119 °C), it attains a maximum coefficient of performance (COP) of 1.68. When the ambient temperature rises to 67 °C, the system delivers a heating supply temperature of 214 °C, with the corresponding COP and relative Carnot efficiency reaching 1.5% and 45.2%, respectively. These findings verify the potential of this system for high-temperature heat pump applications and highlight its advantages under extreme operating conditions.

We report a dual-modal perovskite photodetector by incorporating YbCl3 as a dopant, which simultaneously achieves neuromorphic behavior and conventional optoelectronic properties. Systematic characterizations of doping manipulation reveal that 0.5% YbCl3 can optimally modulate film crystallinity, enhance carrier transport, and tune charge dynamics. Notably, the 0.5% doped device exhibited distinct wavelength-dependent photoresponse, and hallmarks of depression-like neuromorphic behavior are were observed under pulsed 905 nm light excitation. This behavior is clearly supported by negative photoconductivity, gradual baseline modulation, and a prolonged post-illumination tail. However, these adaptive current dynamics are absent under 635 nm light illumination; the device instead demonstrated enhanced photoresponse, with responsivity increasing from 0.45 to 0.73 A/W and detectivity from 1.4 × 1012 to 5.1 × 1012 Jones. This spectral contrast originates from the wavelength-dependent activation of Yb3+-related trap states, confirmed by photoluminance measurements.
