The inevitable crystalline defects and bandgap structure are challenging diamond in the coming electronics and optoelectronics. In this work, the type-II heterojunction of diamond is demonstrated to be transformed from the easy construction of type-I heterojunction by assistance of crystalline defects, benefiting to smart self-powered broadband photodetector. The as-fabricated photodetector exhibits

Cr is essential for enhancing corrosion and oxidation resistance in advanced metallic systems. However, high Cr content may promote the formation of coarse Cr-rich phases (e.g. σ phase), which significantly deteriorate the mechanical performance. Currently, a type of nano-sized Cr-rich precipitates was detected with homogeneous distribution and coherent structure in multi-principal element alloys (MPEAs)

Cooling is essential for electronic devices, ensuring their safe and stable operation, especially under sunlight due to solar heating at high ambient temperatures. Traditional cooling strategies, such as air-conditioners, forced convection with air and water, require the use of extensive power and additional instruments. Recent breakthroughs in materials and structural design for passive cooling, particularly

Direct Z-scheme photocatalytic systems based on SnC/As2S3, SnC/As2S2Se, and SnC/As2SSe2 van der Waals heterostructures are systematically investigated using density functional theory. Comprehensive analyses are conducted on structural stability, electronic and optical properties, strain-modulated solar-to-hydrogen (STH) efficiency, and the Gibbs free energies of hydrogen and oxygen evolution reactions

We develop a new model for phase transformation kinetics in metals by generalizing the Levitas-Preston (LP) phase field model of martensite phase transformations (see Levitas and Preston (2002a,b) and Levitas et al. (2003)) to arbitrary pressure. Furthermore, we account for and track: the interface speed of the pressure-driven phase transformation, properties of critical nuclei, as well as nucleation

Enhancing near-room-temperature p-type (Bi, Sb)2Te3 has long been hindered by an intrinsic trade-off in nano structure interfacial engineering: incoherent interfaces strongly scatter phonons but penalize carrier transport, whereas coherent interfaces preserve mobility but provide limited phonon scattering. Here we propose an in-situ multifunctional interfacial strategy enabled by PbS quantum dots (QDs)

Hydrogen-based direct reduction of iron oxides is strongly influenced by interfacial mass transport, yet the atomic-scale mechanisms remain insufficiently understood. In this work, molecular dynamics simulations based on the atomic cluster expansion (ACE) potential were employed to investigate the stability and transport behavior at wüstite/iron interfaces. The results show a pronounced orientation

The deformation heterogeneity at the grain scale of a ferrite (α) + austenite (γ) dual phase steel was quantitatively investigated based on the slip deformation behavior between adjacent grains. A slip transfer parameter (ktf), formulated from multi-slip systems and slip rates of activated slip systems, was developed to quantify deformation heterogeneity at grain boundaries and phase boundaries. This

We report the magnetic and magnetocaloric responses of SrGd2Al2O7 single crystals, a Ruddlesden-Popper oxide that exhibits intrinsic A-site cation disorder. Structural analysis reveals significant Sr-Gd intermixing, which suppresses long-range magnetic order down to at least 2 K and preserves the full magnetic entropy reservoir of Gd3+. To describe the magnetization behavior, we implement a Gaussian-averaged

The Sm–Pd(111) and Sm-graphene-Pd(111) interfaces have been investigated by X-ray photoelectron spectroscopy (XPS), Ultraviolet photoelectron spectroscopy (UPS), and Low energy electron diffraction (LEED). For Sm–Pd(111) a mixed interface was observed as Sm was deposited on the Pd substrate at ambient temperature. Monolayer (ML) graphene was grown on Pd(111) by exposure to ethylene at elevated temperatures

Heteroatom-doped micro/mesoporous functional polymer-derived carbons with uniform pseudocapacitive sites and enhanced ion storage/transport, are among the most promising supercapacitor electrodes. However, conventional soft/hard templating polymerization combined with carbonization and activation always suffers from poor template-monomer wetting and/or from activation-induced heteroatom loss, limiting

MoS2 is a promising material for metal-ion batteries due to its layered structure and high theoretical capacity. Low electrical conductivity and poor reversibility of the conversion reaction are the main disadvantages of pure MoS2 anodes, which can be overcome by doping with heteroatoms. In this work, we use quantum–chemical calculations to study the effect of nitrogen incorporation into the MoS2 lattice
