An environmentally friendly cellulose-based self-supporting memristor and its preparation method

Abstract

The invention relates to an environment-friendly cellulose-based self-supporting memristor and a preparation method thereof, belonging to the technical field related to semiconductor information. The memristor comprises a flexible substrate, a bottom electrode layer, a functional layer and a top electrode from bottom to top; the flexible substrate is a regenerated cellulose film, and the functional layer is a cellulose film. The cellulose-based self-supporting memristor prepared by the invention solves the problems that the traditional silicon-based memristor cannot be prepared in a large area, the process is cumbersome and harmful to the environment. The material used in the invention is an environment-friendly natural polymer material with wide sources, simple preparation process, low cost, non-toxic and pollution-free environment, and provides a new preparation method for large-area preparation of flexible organic memristors.

Description

An environmentally friendly cellulose-based self-supporting memristor and preparation method thereof technical field The invention belongs to the relevant technical field of semiconductor information, more specifically, relate to a kind of environment-friendly cellulose Self-supporting memristor and method of making the same. Background technique [0002] Memristor, also known as memristor, was first proposed by Professor Cai Shaotang of the University of California in 1971. The fourth passive electronic device besides resistance, inductance and capacitance. Since 2008, HP Labs has experimentally verified memory for the first time. After the existence of the resistor model, memristors quickly gained the attention of the scientific and business communities. The memristor, with its simple structure, The advantages of low power consumption and high storage density have become a research hotspot in the field of semiconductor information and materials. [0003] The prepar...
