Silicon-on-insulator slot-waveguide design trade-offs
International Conference on Photonics, Optics and Laser Technology, 2015 Silicon-on-insulator slot-waveguide structures are designed and analysed numerically. We present our theoretical investigation of field confinement factors and effective nonlinear areas for different waveguide structures in order to find optimized ...

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Advanced Functional Materials, EarlyView.From a database of 170 pentagonal 2D materials, 4 candidates exhibiting altermagnetic ordering are screened. Furthermore, the spin‐splitting and unconventional boundary states in the pentagonal 2D altermagnetic monolayer MnS2 are investigated. A MnS2‐based altermagnetic tunneling junction is designed and, through ab initio quantum transport simulations,

A Transparent Semicrystalline Polymer Used in Thermally Responsive Smart Window Application
Advanced Functional Materials, EarlyView.A thermally responsive smart window is fabricated based on a transparent semicrystalline polymer via copolymerizing stearyl acrylate and ethoxylated trimethylolpropane triacrylate. The high transparency is achieved by restricting the crystal domain to nanometer size via ultraviolet curing at a high temperature.
