Ultrathin high-performance circular polarizers based on MoOCl2/NbOCl2 van der Waals heterostructures

Circularly polarized light (CPL) holds immense promise for diverse applications, including 3D displays, quantum information processing, biosensing, and optical imaging. However, high-performance, ultrathin, and easily integrable devices for CPL manipulation and discrimination rem...

Universal Metal Electrode Contacts in Perovskite Solar Cells via Fermi‐Level Pinning at Yb‐Doped n + Fullerene Interfaces

ABSTRACT Efficient electron extraction at the electron transport layer (ETL)/metal interface is critical for high‐performance perovskite solar cells (PSCs), which is fundamentally governed by interfacial energy‐level alignment; however, the microscopic mechanism by which low‐resi...

Atomic‐Scale Mechanisms of Anisotropic Thermal Decomposition in GeSn Alloys With Stepwise Pinning

ABSTRACT Thermal decomposition of GeSn layers detrimentally affects device performance, while the governing mechanisms remain shrouded by the presence of SiO 2 passivation. In this work, we elucidate the atomic‐scale decomposition of GeSn during thermal degradation using in situ...

Dynamically Tunable Exciton‐Photon Coupling via Multi‐Physics Field in Transition Metal Dichalcogenide Microcavities

ABSTRACT Atomically thin transition‐metal dichalcogenides (TMDs) host tightly bound excitons with large oscillator strengths, making them ideal for studying light‐matter interactions and polaritonic devices. When integrated with optical microcavities, TMD monolayers and van der W...
