Brain-like device capable of carrying out memory enhancement and cognitive identification of nerve cells, and preparation method thereof

Abstract

The invention discloses a brain-like device capable of carrying out memory enhancement and cognitive identification of nerve cells, and a preparation method thereof. The device takes an Si substrate GaN base wafer as a carrier and comprises a silicon substrate layer, an epitaxy buffer layer arranged on the silicon substrate layer, an n-GaN layer arranged on the epitaxy buffer layer, an emitting electrode and a collector electrode, wherein the emitting electrode and the collector electrode are arranged on the n-GaN layer and have the same structure; the emitting electrode and the collector electrode independently comprise an upper table board, the n-GaN layer, an InGaN/GaN quantum well, a p-GaN layer and a p-electrode, wherein the n-GaN layer, the InGaN/GaN quantum well, the p-GaN layer and the p-electrode are connected in sequence and are arranged on the upper table board; the emitting electrode is independently connected with the collector electrode through waveguide; and a hollow cavity is arranged below the n-GaN layer to enable a photo-induced synapsis transistor and the waveguide to hang in the air. By use of the device, photons can be used for replacing electrons or protons to serve as an information carrier to simulate the transmission of neurotransmitters, the time accumulation, the spatial accumulation and the time-space mixing accumulation of a human brain as well as an identification effect can be simulated, and a foundation is laid for researching complex brain memory characteristics.

Description

Technical field [0001] The invention belongs to the field of life sciences and semiconductor devices, and relates to a brain-like device for memory enhancement and cognitive recognition of neurons and its preparation technology. Background technique [0002] In 2000, Gerald M. Edelman, the Nobel Prize winner in Physiology or Medicine, said that the knowledge of brain science will lay the foundation for the coming new era. At present, human brain scientific research is receiving more and more attention from all over the world. Governments all over the world put forward their own "Brain Project": In 2013, the European Union launched the "Human Brain Project", which focuses on medical, neuroscience and Computer technology; in the same year, the United States launched the "BRAIN Initiative" to develop and explore the brain to obtain new discoveries in brain science; in China, the Chinese Academy of Sciences proposed the "Chinese Brain Project" in 2014, based on exploring the mysterie...

Problems solved by technology

These two artificial synapse technologies use electrical signals to transmit stimulation. Compared with the human brain, the power consumption is large, the calculation speed is low, the structure is simple, and the function is limited, which cannot be well adapted to the rapidly developing market.
