A AgS-island network is fabricated with surrounding electrodes to enable it to be used as a reservoir for unconventional computing. Local conductance change occurs due to the growth/shrinkage of Ag filaments from/into each AgS island in the reservoir. The growth/shrinkage of Ag filaments is caused by the drift of Ag cations in each AgS island, which results in a unique non-linear response as a reservoir, especially at lower frequencies. The response of the reservoir is shown to depend on the frequency and amplitude of the input signals. So as to evaluate its capability as a reservoir, logical operations were performed using the subject AgS-island network, with the results showing an accuracy of greater than 99%.
构建了一个带有周围电极的AgS岛网络，使其能够用作非常规计算的存储库。由于银细丝在存储库中从每个AgS岛生长/收缩进入，导致局部电导发生变化。银细丝的生长/收缩是由每个AgS岛中银阳离子的漂移引起的，这使得该存储库产生独特的非线性响应，尤其是在较低频率下。结果表明，该存储库的响应取决于输入信号的频率和幅度。为了评估其作为存储库的能力，使用该AgS岛网络进行了逻辑运算，结果显示准确率超过99%。
