High-fidelity fabrication of sub-millimeter thickness silica glass optical components via a synergistic suppression strategy in UV imprint lithography

Ultraviolet imprinting technology offers significant advantages in fabricating silica glass optical devices due to the high precision, high efficiency, and excellent reproducibility. However, when fabricating components with sub-millimeter thickness and high aspect ratios, the st...

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...

A Fully‐Connected Chip‐Integrated Reconfigurable Mode‐Pairing Quantum Key Distribution Network

ABSTRACT Quantum key distribution (QKD) provides an information‐theoretic security framework for building QKD networks (QNs). However, existing QN architectures face critical challenges: trusted‐node‐based designs inherently expose relay nodes to physical compromise, while entang...
