Advanced Materials | ZEPTOOLS In Situ TEM Reveals Microscopic Resistive Switching Mechanism of Diamond Memristor for Extreme Environments
Inspired by the human brain, neuromorphic computing and artificial synaptic devices offer significant advantages including low power consumption, high speed, and in-memory computing. However, conventional oxide-based resistive switching memories face severe stability challenges under extreme conditions such as high temperatures. Diamond, with its ultra-wide bandgap, exceptional thermal conductivity, and outstanding chemical stability, is recognized as an ideal semiconductor material for developing extreme-environment electronics. Current explorations of diamond-based synaptic devices primarily rely on photoelectric effects, heterojunction barrier modulation, or doping modification strategies to achieve resistive switching characteristics.
