This paper reports the successful fabrication and comprehensive temperature-dependent characterization of MOCVD-grown quasi-vertical AlN Schottky barrier diodes on bulk AlN substrates, demonstrating high current densities, stable rectification up to 300°C, and identifying Poole-Frenkel emission and an interfacial AlNxOy layer as key factors governing their carrier transport and leakage mechanisms.
This paper presents a Zr concentration-dependent sub-lattice phase-field model that successfully explains the ferroelectric-to-antiferroelectric transition in Hf1-xZrxO2 by capturing the competition between orthorhombic and tetragonal phases and revealing how intermediate Zr concentrations lead to mixed-phase states and gradual polarization switching due to local electric field variations.
This study utilizes density functional theory to reveal that the robust ferromagnetic insulating state in strained LaCoO₃ films arises from a unique ordered array of high-spin and low-spin Co³⁺ ions, where ferromagnetic superexchange interactions mediated by low-spin ions overcome competing antiferromagnetic forces to stabilize the ground state.
This study investigates the stability and electronic properties of alkali-triel-pnictide clathrates (ATPn) through high-throughput density functional theory and molecular dynamics simulations, revealing that guest ionization potential and spin-orbit coupling are critical for stability while noting that targeted synthesis of these phases remains unsuccessful.
H-NESSi is an open-source software package that enables efficient, long-time simulations of strongly correlated quantum systems out of equilibrium by combining high-order time-stepping with hierarchical low-rank compression techniques to overcome the prohibitive computational scaling of conventional Kadanoff-Baym equation solvers.
This paper demonstrates that the low-symmetry van der Waals semiconductor CrPS exhibits pronounced room-temperature optical and optoelectronic anisotropy, including strong linear dichroism and polarization-sensitive photocurrents driven by Cr d-orbital transitions, establishing it as a promising platform for narrow-band polarized photodetectors and 2D spintronic devices.
This paper presents a novel coupled fully kinetic hydrogen transport and ductile phase-field fracture framework that successfully models hydrogen embrittlement by capturing the critical role of dislocation segregation and the competition between loading rates and diffusion kinetics, thereby reproducing experimental observations of crack initiation shifts, multiple surface cracking, and the transition from ductile tearing to brittle fracture.
This paper introduces a physics-informed, interpretable linear framework that integrates compositional, orbital, and crystallographic descriptors to rapidly and accurately identify topological materials, overcoming the limitations of composition-only heuristics by distinguishing polymorphs and enabling high-throughput discovery where conventional symmetry indicators fail.
This study reveals that while niobium primarily governs the evolution and symmetry of martensite in Ti-Nb-O alloys by stabilizing the phase, oxygen distinctly modifies transformation pathways by suppressing phase formation at lower niobium levels but inhibiting long-range martensitic transformation at higher levels due to local lattice distortions.
This paper demonstrates the controlled fabrication of VO nanocylinders with tailored phase transition hysteresis via lithographic patterning and dewetting, offering a scalable pathway for energy-efficient neuromorphic photonic memory devices.
