Highly Stable and Non‐Volatile Optoelectronic Synapses for Sensing, Memory, and Computing Enabled by a Deep‐Potential Floating Gate

Advanced Science, EarlyView.
A deep‐potential metal floating gate integrates electrical programming, optical partial erasure, and synaptic weight modulation in a MoS2/h‐BN/Au transistor. The device provides a 97.6 V memory window, retention beyond 3000 s, endurance over 1600 cycles, and reproducible operation after 200 days of ambient storage.

Opposite Trap‐State Evolution Pathways Govern Endurance and Retention Failure in Amorphous Chalcogenide Memory

Advanced Science, EarlyView.
GeSbSe selector‐only memory devices are investigated through physical and electrical analyses to reveal opposite trap‐state evolution pathways governing reliability degradation. Endurance cycling drives Se migration, transitioning traps from deep to shallow states.

Novel Optical Functionalities in Memristors

Advanced Electronic Materials, EarlyView.
We present a tunnel junction memristor with expanded optical functionalities enabled by the integration of an ultra‐thin CdS barrier and a top ITO electrode. UV illumination triggers a photovoltaic response that can sense the memristor state. At very low temperatures, the UV light generates a high injection of photocarriers and produces a volatile ...

Silicon Nitride Resistive Memories

Advanced Electronic Materials, EarlyView.
Amorphous SiNx is an attractive resistance switching material for ReRAM applications due to its physicochemical properties, such as humidity resistance, low oxygen diffusivity, and is used as a metal diffusion blocker. By modifying the ratio between N and Si atoms, the microstructure of the SiNx is affected, rendering it possible to change the ...
