Exciton Radiative Lifetimes in Hexagonal Diamond Ge and SixGe1–x Alloys
Advanced Optical Materials, EarlyView.Strong room‐temperature photoluminescence reported in hexagonal Ge conflicts with theory predicting a nearly dark band edge. First‐principles calculations of excitonic radiative lifetimes fill a key gap in this debate, showing that pristine hexagonal Ge remains intrinsically weakly emissive, while Si alloying only modestly shortens the lifetime and ...

Advanced Optical Materials, EarlyView.An ultrathin Sr interlayer is introduced as a charge‐generation assist layer to overcome the electron‐injection barrier in deep‐LUMO charge‐generation layers (CGLs) of tandem OLEDs. The Sr layer facilitates trap‐assisted tunneling and lowers the effective injection barrier, enabling improved charge balance and yielding tandem OLEDs with doubled ...

Google QUIC performance over a public SATCOM access [PDF]
, 2019 Google QUIC accounts for almost 10% of the Internet traffic and the protocol is not standardized at the IETF yet. We distinguish Google QUIC (GQUIC) and IETF QUIC (IQUIC) since there may be differences between the two.

Room Temperature Anisotropic Photoresponse in Low‐Symmetry Van der Waals Semiconductor CrPS4
Advanced Optical Materials, EarlyView.ABSTRACT The crystalline and optical anisotropy of low‐symmetry 2D materials can enable strong dichroic responses, enhancing polarization contrast for photonic and optoelectronic devices. Here, we unveil pronounced optical and optoelectronic anisotropy in chromium thiophosphate (CrPS4) arising from the strong coupling between light polarization and its

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field
Advanced Robotics Research, EarlyView.This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its
