Convergence Analysis and Error Propagation of the Laplace Residual Power Series Method for Linear Delay Matrix Differential Equations

Xiaotong Ma, Wei Li

Matrix differential equations with time delay are crucial to the modeling of complex multivariate systems. However, the existing semi-analytic Laplace residual power series method (LRPSM) literature mainly focuses on scalar or no-delay problems, and lacks rigorous theoretical guarantees for matrix-valued time delay …

Revisiting Iron's Role in Nature to Fabricate Functional Elastomer With Tunable Mechanical Properties and Promising Optical Applications

Junyi Chen, R A N Xu, Chengfeng Ma, Wei Li et autres

ABSTRACT Plant growth in nature is highly dependent on sunlight. Plants grown under low‐light conditions often exhibit leaf yellowing. This phenomenon occurs because Fe 3+ is reduced to Fe 2+ under ultraviolet light, and a deficiency of Fe 2+ impairs the ability …

Single-Atom Ru in CoFe-LDH Drives Efficient Charge Separation on BiVO4 for Solar Water Splitting

Wenhui Deng, Gaoshuang He, Haozhi Zhou, Wenhao He et autres

Abstract Bismuth vanadate (BiVO 4 ) is regarded as a promising photoanode for photoelectrochemical (PEC) water splitting. Despite its advantage in band gap and visible-light response, the BiVO 4 exhibits an unsatisfactory achieving water splitting due to severe charge recombination. Herein, we …

AI-Assisted Composite Etch Model for MPT

Devin Sima, Wei Li, Chuanmin Hu, Shengrui Zhang

For advanced semiconductor nodes, the demand for high-precision patterning of complex foundry circuits drives the widespread use of Lithography-Etch-Lithography-Etch (LELE)-a key Multiple Patterning Technology (MPT)-in Deep Ultraviolet (DUV) processes. However, the interaction between LELE's two Lithography-Etch (LE) cycles makes it very challenging …

A composite model for LELE process

Devin Sima, Wei Li, Tzung-Hua Ying, Shengrui Zhang et autres

Double patterning technology plays an increasingly important role in the DUV process, especially the reduction of nodes makes it indispensable. Among various kinds of double patterning techniques, lithography-etch-lithography-etch (LELE) double patterning is chosen for printing complex foundry circuit designs. For this reason, …
