Intrinsic and Extrinsic Factors Influencing the Dynamics of VO 2 Mott Oscillators
Physical review applied(2023)
摘要
Many biomimetic computing schemes rely on neuronlike spiking devices, but to design practical systems a deeper understanding of device dynamics is still needed. This study identifies major influences on oscillatory time scales of Mott-insulator-based nanoscale devices with carbon nanotube electrodes. In particular, the authors find that current sources and measurement instruments participate in the observed dynamics. The results highlight paths to control spiking behavior, using not only device thermodynamics and size, but also external circuitry.
