Although these applications are dependent on the optical performance, the origin of the optical absorption in electrochromic oxides is not clear. Here, we demonstrate that the electrochromism of all amorphous cathodic electrochromic oxides can be described by a combination of polaron and bipolaron hopping. Based on the valences of the metallic constituents, we model experimental optical absorption spectra by polaron theory and assign two prominent absorption peaks to polaronic and bipolaronic charge transfer excitations. However, in the special case of V2O5, three peaks were necessary to fit the optical spectra. The activation energies of polaronic and bipolaronic hopping were remarkably similar for all the cathodic oxides studied. Within the framework of polaron absorption, V2O5 would be categorized as a cathodic oxide, rather than as a mixed anodic/cathodic material as in the conventional picture. We emphasize that our findings here not only offer a profound understanding of all amorphous cathodic electrochromic oxides but also pave the way for exploring electrochromic oxides with dual-band modulations.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"32 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992197","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}

This study focuses on three-terminal synaptic transistors utilizing graphene and P(VDF-TrFE) to achieve dynamic reconfigurability between excitatory and inhibitory response modes, which are crucial for mimicking biological functions. The devices operate by applying different top gate spikes (±25 V and ±10 V) to modulate the polarization degree of P(VDF-TrFE), thereby regulating the carrier type and concentration in the graphene channel. This results in the effective realization of enhancement and inhibition processes in two neural-like states: excitatory and inhibitory modes, accompanied by good neural plasticity with paired-pulse facilitation and spike-time-dependent plasticity. With these features, the synaptic devices achieve brain-like memory enhancement and human-like perception functions, exhibiting excellent stability, durability over 1000 cycles, and a long retention period exceeding 10 years. Additionally, the performance of the artificial neural network is evaluated for handwritten digit recognition, achieving a high recognition accuracy of 92.28%.

Beyond spintronics, these degrees of freedom can lead to novel quantum effects such as valley-dependent Hall effects and orbital magnetism, which could revolutionize next-generation electronics. However, achieving independent control over valley polarization and orbital magnetism has been a challenge due to the need for large electric fields. A recent breakthrough involving pentalayer rhombohedral graphene has demonstrated the ability to individually manipulate anomalous Hall signals and orbital magnetic hysteresis, forming what is known as a valley-magnetic quartet. Here, we leverage the electrically tunable ferro-valleytricity of pentalayer rhombohedral graphene to develop nonvolatile memory and in-memory computation applications. We propose an architecture for a dense, scalable, and selector-less nonvolatile memory array that harnesses the electrically tunable ferro-valleytricity. In our designed array architecture, nondestructive read and write operations are conducted by sensing the valley state through two different pairs of terminals, allowing for independent optimization of read/write peripheral circuits. The power consumption of our PRG-based array is remarkably low, with only ∼6 nW required per write operation and ∼2.3 nW per read operation per cell. This consumption is orders of magnitude lower than that of the majority of state-of-the-art cryogenic memories. Additionally, we engineer in-memory computation by implementing majority logic operations within our proposed nonvolatile memory array without modifying the peripheral circuitry. Our framework presents a promising pathway toward achieving ultra-dense cryogenic memory and in-memory computation capabilities.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"48 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020498","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 significant progress has been made in understanding the fundamental mechanisms underlying droplet generation in microchannels and in fabricating devices to produce droplets with varied functionality and high throughput, challenges persist along two important directions. On one side, the generalization of numerical results obtained by computational fluid dynamics would be important to deepen the comprehension of complex physical phenomena in droplet microfluidics, as well as the capability of predicting the device behavior. Conversely, truly three-dimensional architectures would enhance microfluidic platforms in terms of tailoring and enhancing droplet and flow properties. Recent advancements in artificial intelligence (AI) and additive manufacturing (AM) promise unequaled opportunities for simulating fluid behavior, precisely tracking individual droplets, and exploring innovative device designs. This review provides a comprehensive overview of recent progress in applying AI and AM to droplet microfluidics. The basic physical properties of multiphase flows and mechanisms for droplet production are discussed, and the current fabrication methods of related devices are introduced, together with their applications. Delving into the use of AI and AM technologies in droplet microfluidics, topics covered include AI-assisted simulations of droplet behavior, real-time tracking of droplets within microfluidic systems, and AM-fabrication of three-dimensional systems. The synergistic combination of AI and AM is expected to deepen the understanding of complex fluid dynamics and active matter behavior, expediting the transition toward fully digital microfluidic systems.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"28 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991882","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}

The underlying mechanism of EKEH relies on the movement of dissolved electrolytes over charged fluid–solid interfaces through confinements resulting in the generation of useful power. The low energy conversion efficiency typically observed in larger (micrometer) confinements can be substantially mitigated by shifting to nanometer and sub-nanometer regimes. This down-scaling unlocks high selectivity and provides unique opportunities to potentially harness Angstrom-scale interactions to maintain and elevate fluid permeability. However, EKEH at sub-nanometric scales remains fraught with considerable challenges in fabrication, economic viability, scaling of power, and maintenance, significantly impeding its advancement. In this review, we detail the electrokinetic processes that drive energy conversion in the presence of pressure, concentration, and temperature gradients. We examine the key factors affecting conversion efficiency and explore the innovative solutions in the recent literature addressing associated challenges. Additionally, we highlight the role of novel nanomaterials and specialized geometries along with new fabrication techniques that enable high permeation without sacrificing selectivity in nanometer and sub-nanometer confinements. Finally, we delve into the major obstacles that EKEH currently faces to reach its full potential of extracting clean and affordable energy and conclude by offering insight into future developmental directions and potential breakthroughs in this rapidly evolving field.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"70 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142989026","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}

The conductivity of various silica films has been studied since the mid-nineteenth century, usually assuming the presence of ionic conductivity. However, in the sense of a wide bandgap semiconductor, the temperature dependence of the resistivity, which ranges over more than four orders of magnitude, can be accurately explained by normal semiconductor behavior under the presumed presence of a deep electron trap/donor residing ∼2.3 eV below the conduction band edge. That is, the conductance is determined by electron motion and not by ions.

Herein, we address the above challenges by proposing a self-excited localized acoustic manipulation methodology based on a piezoelectric micromechanical diaphragm resonator (PMDR). Such a PMDR integrates acoustofluidics and mass sensing functions in tandem on a single device. Particle enrichment is realized within tens of seconds and the limit of detection is enhanced by mitigating common issues such as low capture rate and non-uniform distribution.

In recent years, there has been a surge in research on polarization-sensitive photodetectors that utilize anisotropic two-dimensional (2D) materials. The essence of these 2D polarization-sensitive photodetectors is rooted in the anisotropic characteristics that arise from the asymmetric crystal lattice of the 2D materials in question. This anisotropy is manifested in both optical and electrical behaviors due to the asymmetrical nature of the crystal structure. This article systematically categorizes anisotropic 2D materials and offers an insightful overview of their crystal structures. It also introduces various optical and electrical characterization techniques designed to elucidate the anisotropic properties of these materials. The focus of the article then shifts to detailing the current state of research in the realm of anisotropic 2D material-based polarization-sensitive photodetectors.
