1.4 million Q factor Si₃N₄ micro-ring resonator at 780 nm wavelength for chip-scale atomic systems [PDF]

, 2020
A silicon nitride micro-ring resonator with a loaded Q factor of 1.4 × 10⁶ at 780 nm wavelength is demonstrated on silicon substrates. This is due to the low propagation loss waveguides achieved by optimization of waveguide sidewall interactions and top cladding refractive index. Potential applications include laser frequency stabilization allowing for

Mixed‐Dimensional 0D‐DNA‐2D Heterostructures Beyond van der Waals: A DNA‐Templated Strategy for Optoelectronic Tunability

Advanced Functional Materials, EarlyView.
A two‐step DNA metallization process is presented for the modular assembly of metal sulfide nanoparticles (NPs) on MoS2, with nanoscale control over their separation and ability to concomitantly assemble different kind of NPs. This allowed to tailor the photoinduced electrical response of phototransistors to different wavelengths, according to the ...

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

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.

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation

Advanced Functional Materials, EarlyView.
This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence
