Embodiment 1

[0055] Such as figure 1 As shown, in the nanofluid memristor of the present invention, liquid storage pools are arranged at the left and right ends, and the two liquid storage pools on the same end are connected with micrometer channels, and nanometer channels are arranged between the two micrometer channels. Nano-channels connected to micro-channels can be processed by micro-nano electronic technology.

[0056] Apply KCl solution (concentration of KCl solution can be 100mM for example) on the left side liquid reservoir of device, apply ionic conductor [BMIM][PF6] to the right liquid reservoir, because nanochannel will be to KCl solution under the interaction with KCl solution With ion selectivity, most of the channel is cation-potassium ions. Driven by the voltage, a large number of potassium ions move to generate friction to drive the liquid to flow (this phenomenon is called electroosmotic flow), thereby realizing the interface movement between the KCl solution and the ion...

Abstract

The invention belongs to the technical field of micro-nano electronics, and particularly discloses an interface memristor based on nanofluid and a preparation and application of the interface memristor. The interface memristor comprises a nano-channel and liquid channels respectively used for accommodating a first liquid and a second liquid, wherein the first liquid and the second liquid are different in conductivity and are insoluble, and only the first liquid can enable the nano-channel to generate an ion selection effect on the first liquid. A voltage is applied to the nano-channel, a liquid interface in the nano-channel is driven by an electric field to move, so that the resistance of the nano-channel is changed, or the writing and reading functions of the memristor can be respectivelyrealized by reading the resistance value of the nano-channel corresponding to the current. According to the interface memristor based on the nano-fluid, the nano-fluid formed by the first liquid andthe second liquid in the nano-channel is utilized, and the electric field is utilized for driving two kinds of solutions which are different in conductivity and immiscible to move in the nano-channel,thereby achieving the resistance change, and achieving the construction of the interface memristor based on the nano-fluid.

Description

technical field [0001] The invention belongs to the technical field of micro-nano electronics, and more specifically relates to a nanofluid-based interface type memristor and its preparation and application. The memristor is a nanofluid memristor based on two different conductivity and immiscible solutions, such as a nanofluid memristor based on KCl solution-ionic conductor [BMIM][PF6]; the corresponding preparation and follow-up The specific application process can be to first prepare a channel with nanoscale depth, width, and length through a micro-nano process, and inject two kinds of solutions into the reservoir, and then control the movement of the solution by applying a voltage to achieve resistive switching characteristics. Background technique [0002] Memristor (memristor) is the fourth basic passive electronic device besides resistors, capacitors, and inductors. "Cai Shaotang" first deduced the existence of this element when studying the relationship between charg...
