One‐Step, High‐Removal‐Rate and Low‐Damage Chemical Mechanical Polishing of InP Enabled by Hydrolysis Activated PF6− with In Situ Fluoride Passivation

Advanced Science, EarlyView.
In this work, we propose a CMP method for InP using NH4PF₆, which hydrolyzes under In3+ catalysis to form reactive species. These convert InP into low‐binding‐energy fluorides, facilitating removal and dissolution. The process delivers high material removal rates, smooth surfaces, and fluorine passivation that lowers defect density and improves ...

Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices

Advanced Science, EarlyView.
Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...

Shadow‐Calibrated Stereo Vision for Colorimetric Sweat Analysis

Advanced Science, EarlyView.
By establishing a mathematical model that reconstructs 3D structures through geometric features of object shadows under controlled illumination, and combining it with Convolutional Neural Network‐based 2D image analysis for volumetric calibration, this work enables highly accurate 3D morphological reconstruction.
