Design and Fabrication of Guiding Patterns for Topography‐Based Searching of 2D Devices for Scanning Tunneling Microscopy Measurements
ABSTRACT We report the design and fabrication of guiding patterns for topography‐based searching of two‐dimensional (2D) devices for scanning tunneling microscopy (STM) measurements. Sub‐micron geometric coordinate markers were etched into SiO 2 /Si wafers, serving as both substrates for 2D device integration and guid…
Programming the Vacuum: A Unified Hamiltonian Engineering Framework for Optimization and Spectral Synthesis
The exponential growth of Hilbert space dimensions presents a fundamental barrier to the classical simulation of quantum systems, necessitating a paradigm shift from algorithmic simulation to physical instantiation. This study validates the “Inverted Church-Turing-Deutsch” (CTD) framework, which posits that physical H…
Highly anisotropic nonrelativistic charge-to-spin conversion in altermagnets
The charge-to-spin conversion provides an efficient way to manipulate the magnetization by electrical means. In this work, we report on a study on the anisotropic nonrelativistic charge-to-spin conversion response to the current direction in altermagnets. We prove that the spin conductivity dictating the charge-to-spi…
Convolutional LSTM surrogate for mesoscale hydrocode simulations of granular wave propagation
Granular materials subjected to impact loading exhibit heterogeneous spatiotemporal dynamics governed by stress-wave propagation, pore collapse, and grain-scale rearrangement. Mesoscale hydrocodes can resolve these mechanisms, but the computational cost of repeated simulations limits parametric studies, uncertainty qu…
Morphogenesis of bacterial colonies in liquid crystalline environments
Natural bacterial habitats are often complex fluids with viscoelastic and anisotropic responses to stress; for example, they can take the form of liquid crystals (LCs), with elongated microscopic constituents that collectively align while still retaining the ability to flow. However, laboratory studies typically focus…
Arduino-controlled pulse electrodeposition for low-cost zinc coating on stainless steel
Abstract Metal corrosion is a major challenge in the manufacturing sector. Pulse electrodeposition (PED) is a promising effective technique for metal corrosion protection; however, the coating quality depends on the PED parameters. This study involved metal corrosion protection research and aimed to improve the qualit…
Broad spectral photosensitivity from visible to shortwave infrared enhanced by annealing the heterojunction of germanium nanoparticles embedded in a silicon nitride layer on silicon
The structural, optical, and optoelectronic properties of germanium nanoparticles (Ge-NPs) in a silicon nitride (Si3N4) are studied for applications across the visible to short-wave infrared range (VIS-SWIR). Ge-NPs:Si3N4 films with a 70:30 volume ratio have been fabricated by magnetron sputtering on c-Si substrate an…
Bidirectional Allosteric Ligand Regulation in a Central Glycolytic Enzyme
Abstract Allosteric regulation enables fine-tuned control of enzyme activity in response to cellular signals, yet its molecular basis often remains unclear. Phosphofructokinase-1 (PFK), the highly conserved, rate-limiting glycolytic enzyme, is a paradigm for Monod–Wyman–Changeux allosteric kinetics. However, X-ray cry…
Bioinspired laser-textured aluminum surfaces for anti-icing
Natural water-repellent surfaces use hierarchical texture and low surface energy to minimize liquid adhesion, and this principle has inspired engineered superhydrophobic surfaces for passive anti-icing. However, whether such bioinspired water-repellent architectures remain beneficial during freezing and ice detachment…
Bayesian Optimization for Practical H2 Sensors: Inverse Design of Pd-based Plasmonic Metasurfaces
Hydrogen detection is becoming increasingly important as its use grows across energy and industrial systems. Optical sensing platforms based on palladium (Pd) nanoparticles are attractive for this task because hydrogen uptake directly alters their plasmonic response. Organizing such nanoparticles into periodic two-dim…
Coupled-cluster molecular properties across the main group that extrapolate beyond training size
Coupled-cluster theory defines the accuracy standard for molecular electronic-structure properties but scales too steeply for routine application, whereas density-functional theory is affordable yet systematically biased. We resolve this trade-off with a single equivariant network, MEHnet-MG, that predicts an effectiv…
Localized Excitons and Exciton-Phonon Coupling in Antiferromagnetic AgCrP2S6
AgCrP2S6 combines a low-symmetry thiophosphate framework with an antiferromagnetic Cr sublattice and nonmagnetic Ag sites, providing a setting in which covalency and magnetic localization compete in the low-energy optical response. We combine single-crystal x-ray diffraction, Raman spectroscopy, lattice-dynamical calc…
A Comprehensive Review of Large Language Models for Nanophotonics: From Surrogate Modeling to Autonomous Design
Metasurfaces have revolutionized the development of photonic devices by enabling unprecedented precision in light manipulation. However, their design processes are often constrained by computationally expensive simulations and complex high-dimensional design spaces. Although deep learning has accelerated the design pr…
Isolating the natural edges of bilayer graphene in gate-defined mesoscopic devices
We introduce a graphite-gated architecture for bilayer graphene devices in which the active device is completely isolated from the natural graphene edges. Using a single patterned graphite-gate layer, we realize a fully electrostatically defined Hall-bar. Longitudinal and Hall measurements reveal mesoscopic transport…

Optical Voltage Profiling of 2D Semiconductors via Proximal Exciton Sensing
High contact resistances in atomically thin semiconductors often mask intrinsic electrical transport properties, particularly at low carrier densities where exotic correlated states emerge. We introduce optical voltage profiling, a noninvasive wide-field technique that replaces local voltage probes with a proximal mon…

Spin defects in silicon carbide (SiC) are promising candidates for integrated quantum photonics, offering long-lived spin states and near-infrared emission suitable for low-loss photonic integration and fibre-based quantum communication. However, light extraction from these defects remains challenging due the relative…
