Recently, all-dielectric metasurfaces (MSs) governed by the physics of bound states in the continuum (BICs) have emerged as a standout platform for delivering high-quality (Q) factor resonances and near-field electromagnetic hotspots. However, in the terahertz (THz) domain, experimental validation of high-Q BICs resonances with strong robustness and advanced maneuverability in such all-dielectric photonic systems remains a long-standing challenge. Here, we demonstrate a simple and feasible fabrication approach to unlock the full potential of BICs-inspired resonances within the array of silicon cross elliptical resonators. Our results suggest that the designed THz-MS can support two symmetry-protected BICs with a topological charge of ±1 and several accidental BICs with a topological charge of +1 simultaneously. By introducing small perturbations to the individual resonator, the original two symmetry-protected BICs transform into quasi-BICs that bow to the inverse-square law. Astoundingly, for larger symmetry breaking, two additional BICs can be observed in the asymmetric THz-MSs surpass typical inverse-square rule, hence presenting a supererogatory degree of freedom for tailoring BICs resonances on demand. We bear out theoretical findings by transmission experiments implemented on the fabricated samples. We observe experimentally ultrasharp dual quasi-BICs resonances with a highest measured Q factor of up to 371, a level of performance that was previously unattainable with all-dielectric THz-MS on a substrate. The results mark an important step toward enriching the family of BICs and promise exciting opportunities in the field of THz optoelectronic devices and metadevices.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"20 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

Here, we establish for the first time the intrinsic evolution laws of Fabry–Pérot bound states in the continuum (FP-BICs), revealing that the Q factor is inversely proportional to the square of phase/frequency detuning and to the nonradiative decay rate, enabling directional engineering of FP-BIC resonances. We propose an all-dielectric multilayer film metasurface to create an optical resonator and its perfectly mirrored counterpart, inducing FP-BICs and validating the conclusions. We experimentally demonstrated the evolution of the Q factor with frequency detuning, achieving a maximum Q factor of 610 in the visible.

Among the different growth methods, chemical vapor deposition (CVD) offers high flexibility and has demonstrated the ability to produce oxide films hosting rare-earth ions with narrow linewidths. However, growing epitaxial films directly on silicon is challenging by CVD due to a native amorphous oxide layer formation at the interface. In this manuscript, we investigate the CVD growth of erbium-doped yttrium oxide (Er:Y2O3) thin films on different substrates, including silicon, sapphire, quartz, or yttria stabilized zirconia (YSZ). Alternatively, growth was also attempted on an epitaxial Y2O3 template layer on Si (111) prepared by molecular beam epitaxy (MBE) in order to circumvent the issue of the amorphous interlayer. We found that the substrate impacts the film morphology and the crystalline orientations, with different textures observed for the CVD film on the MBE-oxide/Si template (111) and epitaxial growth on YSZ (001). In terms of optical properties, Er3+ ions exhibit visible and IR emission features that are comparable for all samples, indicating a high-quality local crystalline environment regardless of the substrate. Our approach opens interesting prospects to integrate such films into scalable devices for optical quantum technologies.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"171 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143660479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}

These atomically thin materials exhibit strong light–matter interactions and large nonlinear responses, thanks to their tunable lattice symmetries, strong resonance effects, and highly engineerable band structures. In this paper, we explore the potential that 2D materials bring to nonlinear optics, covering topics from classical nonlinear optics to nonlinearities at the few-photon level. We delve into how these materials enable possibilities, such as symmetry control, phase matching, and integration into photonic circuits.

Recent advancements in both direct and indirect 3D bioprinting offer promising solutions to construct complex vascular networks by allowing precise control over cell and extracellular matrix placement. The process from shape printing of microvasculature to function formation involves dynamic shift of bioink mechanical properties, mechanical microenvironments, and mechanobiology of endothelial and supporting cells. This review explores how biomechanical and mechanobiological principles are integrated into the bioprinting process to develop functional microvascular networks. Before printing, a top-level design approach based on these principles focuses on the interactions among biomaterials, cell behaviors, and mechanical environments to guide microvascular network fabrication. During printing, biomechanical design of bioinks for different bioprinting techniques, along with optimized biomechanical factors of bioprinting process, ensures accurate microvascular structure reproduction while maintaining cell viability. After printing, the emphasis is on creating a suitable mechanical environment to modulate the mechanobiology of multiple steps of neovascularization, including initiation, morphogenesis, lumen formation, stabilization, and maturation of functional microvasculature. Finally, we discuss future developments based on biomechanical and mechanobiological design to drive the bioprinting of functionalized microvascular networks.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"19 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 the intelligence of biomaterials has evolved from inert to active over the past few decades, smart biomaterials take this a step further by making their surfaces or bulk respond based on interactions with surrounding tissues, imparting outcomes similar to natural tissue functions. This interaction with the surrounding tissue helps in creating stimuli-responsive biomaterials, which can be useful in tissue engineering, regenerative medicine, autonomous drug delivery, orthopedics, and much more. Traditionally, material engineering focused on refining the static properties of biomaterials to accommodate them within the body without evoking an immune response, which was a major obstacle to their unrestricted operation. This review highlights and explains various engineering approaches currently under research for developing stimuli-responsive biomaterials that tune their outcomes based on responses to bodily factors like temperature, pH, and ion concentration or external factors like magnetism, light, and conductivity. Applications in soft and hard tissue engineering, 4D printing, and scaffold design are also discussed. The advanced application of microfluidics, like organ-on-a-chip models, extensively benefits from the intrinsic smart properties of biomaterials, which are also discussed below.

Na1+xZr2SixP3−xO12 (NaSICON) SEs have recently regained attention for applications in both solid-state and aqueous redox flow batteries due to their improved electrochemical and mechanical properties, along with their inherent electrochemical stability, air robustness, and low manufacturing cost. Recent improvements in NaSICON have primarily targeted macroscopic property enhancements and synthesis techniques. To enable further breakthroughs in the performance of NaSICON SEs, future efforts should focus on understanding how modified synthesis conditions influence atomic and microscopic-scale features, such as conduction channels, electronic structures, phase distributions, and grain boundaries. These features ultimately control ion conductivity, mechanical properties, and electrochemical stability of NaSICON and its interfaces. Here, we review the current understanding of the structure-chemistry-property relationships of NaSICON SEs, focusing on atomic and microscopic levels. First, we introduce the proposed ionic conduction mechanisms in NaSICON crystallites. Then, we explore experimental investigations at phase and grain boundaries to assess ionic conduction and interfacial stability. We also examine strategies to address interfacial challenges such as high resistance and chemical reactions between SEs and electrodes, highlighting the difficulties in analyzing interfaces at the nano/atomic scale. Finally, we provide an outlook on advancing microscopy and spectroscopy techniques to enhance insights into NaSICON SEs ionic conduction and interfacial stability, supporting the development of improved long-duration energy storage devices.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"124 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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}
