摘要

为了实现透明神经形态装置可靠的短期记忆，保证可见性和获得合适的放松时间是至关重要的。在这项工作中，我们通过微波处理（MWT）展示了完全透明和可靠的STM器件，它提供了减少应力和高效率的好处。结果表明，MWT提高了器件在可见光区的透过率，延长了器件的弛豫时间。通过对1000 W/120 s MWT过程的松弛时间进行优化，可获得0 ~ 6.95 s的最优松弛余量。此外，我们通过实验实现了一个由16个状态组成的储层计算（RC）系统，该系统可以用4比特和16个状态进行精确分类，从而证明了RC系统的可行性。基于这些结果，我们证实了MWT是一种有效的退火方法，可以帮助优化STM器件的弛豫时间。

Optimizing Short-Term Memory in Transparent Neuromorphic Devices via Microwave Treatment: Enhancing Transmittance and Relaxation Time

It is crucial to guarantee the visibility and attain a suitable relaxation time in order to implement reliable short-term memory (STM) for transparent neuromorphic devices. In this work, we demonstrated fully transparent and reliable STM devices via microwave treatment (MWT), which offers the benefits of reduced stress and high efficiency. It was found that MWT improves transmittance in the visible light region and increases the relaxation time of the device. As a result of optimization of relaxation time in MWT process with 1000 W/120 s, the most optimal relaxation time margin of 0 ~ 6.95 s could be secured. Furthermore, we experimentally implemented a reservoir computing (RC) system that consisted of 16 states that can be precisely classified with 4 bits and 16 states, which thereby proved the RC system’s viability. Based on these results, we confirmed that MWT is an effective annealing method that can contribute to the optimization of the relaxation time in the STM device research.
