AbstractWe have studied the characteristics of frequency response at 850-nm GaAs high-speed vertical-cavity surface-emitting lasers (VCSELs) with different kinds of oxide aperture sizes and cavity length using the PICS3D simulation program. Using 5-μm oxide aperture sizes, the frequency response beh

Abstract Two‑dimensional indium selenide (InSe) has emerged as a promising channel material for future CMOS nodes, offering carrier mobilities around 2 000 cm2/V·s and on/off ratios exceeding 108 in experimental devices. Theoretical work has predicted that InSe field‑effect transistors (FETs) can m

AbstractWe report the different oxidation behavior between polycrystalline chemical-vapor-deposited and mechanically exfoliated single crystal MoS2 monolayers by ultraviolet-ozone treatment. As ultraviolet-ozone treatment time increased from 0 to 5 min, photoluminescence emission and Raman modes of

AbstractDetonation nanodiamonds (DNDs) of <5 nm diameter were shown to host nitrogen‑vacancy (NV⁻) color centers at a concentration of 1.1 ± 0.3 ppm, a record for nanodiamonds with intentionally created NV⁻ centers. The concentration was derived from electron paramagnetic resonance (EPR) using the i

Abstract A new metal‑organic chemical vapor deposition (MOCVD) technique has been developed to grow indium quantum dots (In QDs) directly on the surface of an InGaN epitaxial layer. By applying a two‑step cooling protocol, the In QDs emerge with highly uniform size. Detailed analysis reveals that th

AbstractWe report a one‑pot hydrothermal synthesis that inserts nanoneedle γ‑AlO(OH) into MgAl‑LDH layers, yielding a heterostructure with exceptional adsorption of methyl orange (MO). The interlayer spacing expands from 7.6 Å to 8.77 Å, while abundant –OH groups enhance chemisorption kinetics. The

AbstractWe investigated the optical characteristics and growth pathway of La3Ga5.5Nb0.5O14 (LGN) powders produced by the Pechini sol‑gel method. After calcination at 600–800 °C, X‑ray diffraction confirmed the emergence of a single‑phase orthorhombic LGN structure (JCPDS 47‑0533) at 800 °C. A schema

AbstractThe B2 CuZr phase is frequently incorporated into bulk metallic glasses to enhance toughness, yet its phase‑transformation response under different loading orientations is not fully understood. Using molecular‑dynamics simulations, we examined uniaxial tension and compression of B2 CuZr alon

AbstractInorganic cesium lead halide perovskites, CsPbI3‑xBrx, have emerged as promising materials for photodetectors thanks to their excellent optoelectronic characteristics and the simplicity of solution‑based fabrication. Here, we demonstrate flexible photodetectors fabricated by a modified solut

AbstractWet etching offers an advantage as a soft, damage-less method to remove sacrificial material with close to nanometer precision which has become critical for the fabrication of nanoscale structures. In order to develop such wet etching solutions, screening of etchant properties like selectivi

AbstractStrain engineering offers a practical route to tailor the physical properties of two‑dimensional (2D) materials owing to their exceptional flexibility. In this study, we systematically investigate how biaxial tensile strain influences the electronic, phononic, and thermoelectric properties o

AbstractIn this paper, the structural, electronic, and optical properties of MoS2 multilayers are investigated by employing the first-principles method. Up to six-layers of MoS2 have been comparatively studied. The covalency and ionicity in the MoS2 monolayer are shown to be stronger than those in t

Abstract Nanoparticle drug delivery systems are increasingly crucial for interacting with lymph nodes, where B cells, T cells and natural killer cells orchestrate immune responses. When these cells become malignant, they attack healthy tissue. This study presents an intelligent delivery platform tha

Abstract This work presents a one‑step electrospinning protocol for producing polyacrylonitrile/polystyrene (PAN/PS) micro‑nanofibers that incorporate ammonium metatungstate hydrate (AMT) and cobalt(III) acetylacetonate (Co(acac)3). The fibers exhibit a highly porous surface, a broad distribution o
