Recently,research on two-dimensional (2D) semiconductors has begun to translate from the fundamen-tal investigation into rudimentary functional circuits.In this work,we unveil the first functional MoS2 artificial neural network (ANN) chip,including multiply-and-accumulate (MAC),memory and activation function circuits.Such MoS2 ANN chip is realized through fabricating 818 field-effect transistors (FETs) on a wafer-scale and high-homogeneity MoS2 film,with a gate-last process to realize top gate structured FETs.A 62-level simulation program with integrated circuit emphasis (SPICE) model is utilized to design and optimize our analog ANN circuits.To demonstrate a practical application,a tactile digit sensing recognition was demonstrated based on our ANN circuits.After training,the digit recognition rate exceeds 97％.Our work not only demonstrates the protentional of 2D semiconductors in wafer-scale inte-grated circuits,but also paves the way for its future application in AI computation.

如果将物体分散到无法分析的单位,例如光子,人们就称这样的粒子为量子,而量子纠缠则是指利用某种方法产生几种相关联的量子,不管这几种量子各自彼此间距有多远,内部也并不是同一个介质,只是其中某个量子态的改变将会影响到另一种量子的态.文本主要讲述了量子的特性和量子纠缠的现象,量子纠缠在生物界的存在现象,以及量子纠缠在计算、通讯和军事领域的应用情况,最后探讨量子纠缠可能形成的原因.
