Highly Tunable Schottky Barrier to 2D Semiconductors Enabled by an Inorganic‐Molecular‐Crystal Tunneling Layer

ABSTRACT Effective tuning of the Schottky barrier, which determines charge transport across the metal‐semiconductor interface, is essential for optimizing the performance of electronics and optoelectronic devices. However, interfacial disorders and orbital overlap between metals...

FLASH: Ultrafast Beam Quality Characterization via Spatial‐to‐Temporal Mapping

ABSTRACT Accurate and real‐time monitoring of spatial beam quality is the absolute prerequisite for intelligent optical field regulation and advanced laser applications. However, modern high‐power and multimode laser systems can exhibit rapid pulse‐to‐pulse fluctuations in their...

Buried Layer Enhances Interfacial Dipole Toward Ultrabright Blue Perovskite Light‐Emitting Diodes

ABSTRACT The emerging micro‐displays and visible light communication demand light‐emitting devices capable of simultaneously achieving high efficiency and ultrahigh brightness under high current injection. Lead‐halide perovskite light‐emitting diodes (PeLEDs) are intrinsically ca...

Room-temperature multiferroicity in all–van der Waals heterostructures

Multiferroics host simultaneous and coupled ferroic orders, allowing disparate external stimuli to induce abrupt transformations in their structures and properties. Creating multiferroicity in two-dimensional (2D) van der Waals (vdW) platforms would add the elements of strong qua...

Zoned Namespace is a Double-edged Sword: Rethinking the Impact of the ZNS Interface on File System Scalability

Emerging Zoned Namespace (ZNS) SSDs transfer garbage collection (GC) to the host, thereby providing more stable performance and extending device life. Although the ZNS SSD has these hardware advantages, each zone in the ZNS SSD must be written sequentially. File systems always ne...

Fully tunable on-chip meta-generator for multidimensional Poincaré sphere mapping

Abstract The angular momentum of light can be elegantly mapped onto high-order Poincaré spheres, providing a powerful framework for describing structured light beams. Such beams have shown extraordinary potential across diverse applications, including high-capacity optical commun...
