Tunable small-angle nonreciprocal radiation and broadband absorption in a GST–Weyl semimetal resonant structure
Nonreciprocal radiation is essential for advanced thermal photonics but is constrained by static performance and large incident angle requirements in current Weyl semimetal (WSM)-based devices. Here,...
Transparent perovskite pn junction in ZnCo2O4/SrTiO3 for photoelectric conversion enhancement <i>via</i> barrier transition/upconversion of Tm:Bi2O3 quantum dots
The ZnCo2O4/Tm:Bi2O3 quantum dots/SrTiO3 transparent perovskite pn junction is synthesized via the approach of a hybrid chemical-sol-gel-annealing method. The as-prepared ZnCo2O4/Tm:Bi2O3 QDs/SrTiO3 s...
Tuning atomic structure of single-crystalline diamond surfaces by femtosecond laser for enhanced heat transfer
Diamond offers exceptional thermal conductivity for high-power and wide-bandgap devices, but poor wettability limits its application in liquid-cooling environments. In this work, femtosecond laser irr...
Infrared and visible single-pixel holographic microscope
Holographic microscopy, which enables simultaneous observation of amplitude and phase information from label-free microscale samples, plays a crucial role in biomedical research and materials science....
Electron spin relaxation in bulk GaAs at room temperature: A Monte Carlo-based quantitative study
The electron spin relaxation time is a critical parameter that directly influences the performance of spintronic devices. We investigate spin relaxation in bulk GaAs at room temperature by combining t...
Aggregation modulation of conjugated polymers by carbon dots for optoelectronic synaptic transistors and artificial visual recognition
Developing low-power and highly stable optoelectronic synaptic devices is essential for emulating visual neuromorphic functions. Herein, hydrophobic nitrogen/sulfur-doped carbon quantum dots (N/S-CDs)...
Impact of superlattice size on quantum efficiency and polarization in MOCVD-grown strained GaAs/GaAsP photocathodes
Strained superlattice GaAs photocathodes are crucial for providing high photocurrent beams of spin-polarized electrons at several accelerator facilities including the Continuous Electron Beam Accelera...
Epitaxial growth and substitution control of SrIr1− <i>x</i> Sn <i>x</i> O3 thin films by dual-beam pulsed laser deposition
The emergent antiferromagnetic insulating phase of SrIr1−xSnxO3 has functional spintronic properties but is critically sensitive to the substitution concentration x, which is difficult to precisely tu...
Reduced graphene oxide on α-Ga2O3 with adjustable Schottky barrier for solar-blind UV detection
α-Ga2O3 is a promising material platform for solar-blind ultraviolet photodetectors. Among the various device architectures, metal–semiconductor–metal (MSM) structures are attractive because they offe...
Δ E effect-enabled optomechanical magnetometers for DC magnetic field detection
The detection of direct current (DC) magnetic fields is essential for applications including space exploration, marine monitoring, and seismic study. In this work, we demonstrate a cavity optomechanic...
