Abstract

The invention relates to a preparation method of an artificial synaptic device with a nano channel. According to the method, polyvinyl carbazole and styrene are mixed to prepare a precursor solution, then a nanowire array is printed on a prepared semiconductor layer by using high-resolution electrofluid jet printing equipment, and after an electrode is evaporated, the prepared nanowire array is torn down along the edge of a metal electrode by using an adhesive tape to obtain a nano channel. The nano-channel prepared by the method is controllable in size and orderly in arrangement, can be applied to small-size electronic devices, solves the problem of size limitation of the electronic devices prepared in the prior art, has the advantages of simple operation, simple and convenient process and large-scale preparation, and greatly reduces the energy consumption of the artificial synaptic device with the nano-channel.

Description

Technical field: [0001] The invention belongs to the field of electronic devices, in particular to an artificial synapse electronic device with nano-channels. Background technique: [0002] Neuromorphic engineering is an important means of designing and fabricating non-biological computing systems with highly parallel computing that is highly similar to the human brain. The artificial neuromorphic system simulates various complex functions of the human brain, such as cognition, memory, and calculation, with extremely high budget speed and efficiency. With the development of electronics and information technology, computers are still inferior to the human brain in terms of size, computing speed, and operating efficiency. Therefore, manufacturing computers with similar structures and functions to the brain may be an important direction for future development. [0003] The interconnected neurons constitute the nervous system of the brain, which enables the brain to deal with ...
