Integration of Low‐Voltage Nanoscale MoS2 Memristors on CMOS Microchips

Advanced Functional Materials, EarlyView.
This article presents the first monolithic integration of nanoscale MoS2‐based memristors into the back‐end‐of‐line of foundry‐fabricated CMOS microchips in a one‐transistor‐one‐resistor (1T1R) architecture. The MoS2‐based 1T1R cells exhibit forming‐free, nonvolatile resistive switching with ultra‐low operating voltages, low cycle‐to‐cycle variability ...

Realization and optimization of optical logic gates using bias assisted carrier-injected triple parallel microring resonators

Results in Optics, 2021
We propose a p-i-n diode embedded parallel triple microring resonator (MRR) configuration to simultaneously realize optical OR and AND, or NAND and NOR logic gates using a bias-assisted carrier injection mechanism.

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

All-optical logic gate in silicon nanowire optical waveguides

IET Circuits, Devices & Systems, 2011
In this study, the authors propose a novel optical waveguide consisting of arrays of silicon nanowires (SiNWs) in close proximity for applications to all-optical logic operations. The logic operations are based on two non-linear phenomena, stimulated Raman scattering (SRS) and free carrier absorption (FCA).
