Nanoscale memristor with multiple synaptic mechanisms for energy efficient neural networks
In our recent Nature Communications publication, featured on the Editors' Highlights webpage, we introduce nanoscale memristive devices that combines enhanced synaptic emulation with ultra-low energy consumption. These breakthroughs could improve AI performance and efficiency, with our devices showing a 100x energy reduction compared to GPUs in a neural network playing Atari games.
World-Record Low Switching Energy
We have shown that nanometer-scale VO2-based resistive switches uses as little energies as a few femtojoules for switching, outperforming the energy efficiency of individual neurons in the human brain: S.

ACS Nano, accepted (2024). arXiv:2403.13530.
World-Record Switching Time
We have demonstrated the current world record resistive switching speed and multilevel programming in Ta2O5 based memristors. Switching times down to 10 ps could be measured at picosecond resolution: M. Csontos, Y. Horst, N. J. Olalla, U. Koch, I. Shorubalko, A. Halbritter, J.

Weltneuheit: Atomare Lichtquelle entdeckt
Wer forscht, macht zuweilen völlig überraschende Entdeckungen. So fand das Team um Jürg Leuthold vom Zentrum für Einzelatom-Elektronik und -Photonik an der ETH Zürich heraus, dass manche ihrer Atomschalter auch Licht erzeugen – eine Weltneuheit!
