Problems solved by technology

Professor Cai Shaotang used a bunch of resistors, capacitors, inductors and amplifiers to make a circuit that simulates the effect of memristors. Since the semiconductor technology was not mature enough at that time, he did not find any materials that had obvious memristor effects.

Abstract

The invention discloses a nanowire memristor and a manufacture method thereof. The nanowire memristor comprises an upper electrode, a lower electrode, and a memory storage layer arranged between the upper electrode and the lower electrode. The manufacture method of the nanowire memristor comprises the following steps of: providing an insulation substrate; forming the lower electrode on the insulation substrate; synthesizing a nanowire on the lower electrode to be used as the memory storage layer; and forming the upper electrode on the nanowire memory storage layer. The memory storage layer comprises a single nanowire or nanowire array. The nanowire memristor disclosed by the invention is small in size, can realize more integration, and has a simple structure and is simple in preparation process.

Description

technical field [0001] The invention relates to the technical field of nanometer and memory, in particular to a nanowire memristor and a manufacturing method thereof. Background technique [0002] Memristors are the fourth passive circuit component to enter mainstream electronics after resistors, capacitors, and inductors. figure 1 Shown are resistors, capacitors, inductors, and memristors, four passive circuit component symbol diagrams. The concept of memristor was proposed in 1971 by Cai Shaotang, a Chinese scientist who was teaching at the University of California, Berkeley. When studying the relationship between charge, current, voltage and magnetic flux, Professor Cai Shaotang deduced that besides resistors, capacitors and inductors, there should be a circuit element that represents the relationship between charge and magnetic flux. The resistance of this circuit element will change with the amount of current passing through it, and when the current stops, its resista...
